Peptides

<p>Pyroglutamyl β-Amyloid (4-14) Biotin is derived from Amyloid-β, which has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer's disease (AD) and Down's syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS. Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.This peptide contains a C-terminal Biotin tag that is covalently bonded via ethylenediamine and can be used for detection and purification. Additionally, there is a Pyroglutamyl molecule located at the N-terminal position.</p>

<p>[Sulfo-Cyanine3]-LifeAct (Abp140 1-17) contains the fluorophore sulfo-cyanine3 and the 17 amino acid peptide lifeact derived from amino acids 1-17 of the Saccharomyces cerevisiae actin binding protein, Abp140. These first 17 amino acids of Abp140 are crucial in allowing lifeact to localise to actin filaments (F-actin) and therefore it can be used as a cytoskeletal marker. One application of lifeact is in the study of plant development and pathogen defence as filamentous actin within the plant's actin cytoskeleton is important in key processes such as cell division, membrane trafficking and stomatal movements. The addition of Atto655 which has single molecule (SM) imaging properties allows the location of lifeAct (Abp140 1-17) binding to be detected.</p>

<p>Myelin oligodendrocyte glycoprotein (MOG) is a member of the immunoglobulin (Ig) protein superfamily and is expressed exclusively in the central nervous system (CNS) on the surface of myelin sheaths and oligodendrocyte processes. MOG is expressed at the onset of myelination, and therefore is a potential marker for oligodendrocyte maturation.MOG contains an extracellular domain, a transmembrane domain, a cytoplasmic loop, a membrane-associated region and a cytoplasmic tail.- MOG may function as a cell surface receptor or cell adhesion molecule. -Fifteen different alternatively spliced isoforms have been detected in humans. These are present either on the cell surface, the endoplasmic reticulum in the endocytic system, or in secreted form.The secreted form of MOG may trigger autoimmunity if released into the cerebrospinal fluid and periphery. MOG is thought to be a key target for autoantibodies and cell-mediated immune responses in inflammatory demyelinating diseases such as multiple sclerosis (MS) and is therefore widely studied in this field.Fragment 92-106 of MOG is able to induce experimental autoimmune/allergic encephalomyelitis (EAE), an animal model that resembles MS.</p>

<p>Peptide Fluor-VPMLK-OH is a Research Peptide with significant interest within the field academic and medical research. This peptide is available for purchase at Cymit Quimica in multiple sizes and with a specification of your choice.</p>

<p>Forms of inherited muscular dystrophy such as Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) result from mutations targeting the dystrophin gene. These disorders are X-linked, progressive, and cause the gradual weakening of the muscles leading to respiratory failure and ultimately reduces the patient lifespan.In DMD, mutations lead to the production of premature stop codons and hence the truncated dystrophin protein product is vulnerable to nonsense mediated decay and degradation. Therefore, dystrophin production in muscle cells is reduced. On the other hand, nonsense mutations which also contribute to DMD, cause exon skipping in BMD and result in an internally truncated protein product which are partially functional. The symptoms of BMD are later onset compared with DMD which develop in patients between 2 to 7 years.Treatments of dystrophin disorders are in clinical trial including antisense oligonucleotide exon skipping and gene therapy. However, the efficacies of these treatments are not easily quantified. Currently levels of muscular dystrophin are quantified by western blot which can be unreliable. The peptide provided here, aligning residues dystrophin (2690-2700), has been tested via mass spectrometry to provide a more reliable method of validation of dystrophin levels. Further study with this dystrophin fragment could prove to be a vital step in the understanding and treatment of dystrophin disorders. Within our catalogue we also have other peptides tested for dystrophin quantification available plus the full-length dystrophin protein.</p>

<p>Glucagon (1-29)-[Cys(Cy5)] is derived from glucagon, which is a peptide hormone secreted by alpha cells located in the islet of Langerhans region of the pancreas. Glucagon is an essential catabolic hormone that is responsible for the regulation of blood glucose levels. Once released into the bloodstream, glucagon stimulates the production of hepatic glucose, which means it is considered to be a glucose-mobilizing agent. Excessive levels of glucagon can result in the development of hyperglycaemia, since the action of glucagon results in abnormally high blood glucose levels.This peptide contains Cyanine 5 (Cy5), which is a widely used red fluorescent dye.</p>

<p>Infliximab is a biologic medicine used in the treatment of numerous autoimmune diseases including Crohn disease, rheumatoid arthritis, and ankylosing spondylitis. Infliximab binds with high affinity to tumour necrosis factor-α (TNF-α) blocking most of the cytokine effects, which includes mediating the inflammatory responses. Infliximab is a chimeric human-mouse IgG monoclonal antibody- the constant regions of the heavy and light chains are human-derived. The heavy chain peptide (46-60) has been identified as an antigen for antigen-specific T cell analysis. Numerous methods of immunological analysis can be applied to this peptide to hopefully provide further insight to these autoimmune conditions.</p>

<p>Histone H3 (1-20)-[S]-Biotin is derived from Histone 3 (H3) which is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into a structure known as the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Both H4 and H3 are highly conserved and perform roles in binding to segments of DNA which enter and leave the nucleosome and in chromatin formation. Similar to the other core histone, H3 has a globular domain and a flexible N-terminal domain, 'histone tail' which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination. Due to histones containing a large number of lysine and arginine residues they have a positive net charge which interacts in an electrostatic manner with the negatively charged phosphate groups in DNA. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.Another modification process histones can undergo is biotinylation where the covalent attachment of a biotin molecule is catalysed by the enzyme Biotinidase. This cleaves biocytin to generate a biotinyl-thiester intermediate. The biotinyl can then be transferred onto the histone lysine ɛ-amino group which in this case it is covalently attached to Histone 3. Overall the biotinylation sites identified in histone 3 are: K4, K9 and K18. The presence of biotinylated histones have been detected in human cells such as lymphocytes and lymphomas.</p>

<p>Syntide-2 is a substrate peptide which was specifically designed to be homologous to site 2 in glycogen synthase. Syntide-2 is therefore phosphorylated by Ca2+ calmodulin-dependent protein kinase II as well as other calcium dependant kinases and protein kinase C. Synthase-2 can also be phosphorylated by CAMP-dependent protein kinase and to a lesser extent- phosphorylase kinase, but not by myosin light chain kinase.</p>

<p>SARS-CoV-2 Membrane protein (172-188)</p>

<p>Binds to human transferrin receptor (TfR). This 12-amino acid peptide does not compete with transferrin for receptor binding and is able to internalise into TfR expressing cells.</p>

<p>SAMS peptide was originally designed as a selective substrate for mammalian 5' adenosine monophosphate-activated protein kinase (AMPK) for use in kinase assays. However it is also able to be phosphorylated by the yeast AMP homologue- sucrose non-fermenting 1 kinase (SNF1) and SNF1-related kinases (SnRK1) in plants.The conserved family of kinases containing SnRK1, SNF1 and AMPK plays an important role in regulating cellular energy homeostasis.</p>

<p>Histone H3 (1 - 21) K4Me3 is derived from Histone 3 (H3) which is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Both H4 and H3 are highly conserved and perform roles in binding to segments of DNA which enter and leave the nucleosome and in chromatin formation.

The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.Lysine 4 of Histone H3 (1 - 21) K4Me3 has been tri-methylated.</p>

<p>SARS-CoV-2 ORF3a (26-40)</p>

<p>ANP (1-28) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in cardiovascular remodelling.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in pro-ANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.</p>

<p>ANP (7-23) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis.

The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter to change the positioning of the nucleosome, allowing the DNA it to be either available to the transcription machinery or inaccessible.The Histone H3 (1-14) lysine 4 has been trimethylated and contains 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag.</p>

<p>Kinetensin was originally isolated from pepsin-treated plasma, and it shares some sequence homology with the C-terminal end of neurotensin (NT), having four of its nine amino acids in common with NT. Kinetensin is a potent histamine releaser and therefore may serve as an inflammatory mediator, it also has a role as a human metabolite and can increases vascular permeability. Kinetensin can be cleaved by ACE2.</p>

<p>GSS-acid is a tripeptide consisting of a glycine residue followed by two serine residues. GSS-acid was synthesised from the dipeptide glycyl-L-serine (GS-acid)- the dipeptide GS-acid is also available in our catalogue. GSS-acid has a net charge of 0 and has diverse biological and chemical uses.</p>

<p>The synthetic canonical Flag sequence has been shown to be most effective with the Asp-Tyr-Lys-Xaa-Xaa-Asp motif triplicated for applications in protein analysis followed by the eight amino acids at the C-terminus of the classic FLAG sequence (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys). Due to the hydrophilic nature of the peptide the Flag tag typically resides on the surface of the recombinant protein thus minimising any effects on the function or transport of the fusion protein. The tag can be used in conjunction with other tags such as HA or myc depending on the application. FLAG is an artificial antigen to which high affinity monoclonal antibodies have been raised, therefore allowing for highly effective protein purification by affinity chromatography as well as accurate localisation of FLAG tagged proteins within living cells, or Western blots. FLAG peptide can be used to effectively purify complexes with multiple proteins as its mild purification procedure tends not to disrupt such complexes. It can be used to obtain proteins of sufficient purity for x-ray crystallography. The 3 x Flag peptide provides powerful detection and purification of recombinant proteins that has been characterised in numerous applications including affinity chromatography, binding assays and structural analysis.</p>

<p>Tetanus Toxin P30 (947-967) is a protein that is derived from the single-chain polypeptide neurotoxin produced by Clostridium tetani. The neurotoxins produced by Clostridium tetani are among the most potent molecules known to humankind. Once in the body, the toxin binds to the basal lamina at the neuromuscular junction. From here, the toxin is transported to inhibitory interneurons in the spinal cord, where it prevents the release of neurotransmitters, which causes spastic paralysis.</p>

<p>Pathogenic Staphylococcus aureus strains produce N-formylmethionyl containing peptides. Peptides starting with an N-formylated methionyl group constitute a unique hallmark of bacterial as well as mitochondrial metabolism, and professional phagocytes of our innate immune system recognise this microbial/mitochondrial pattern as a danger signal that guides innate immune cells.All PSMα peptides have the same basic functions and promote virulence through effects on discrete neutrophil functions (i.e. chemotaxis) and by being cytotoxic at higher concentrations. PSMα2 and PSMα3 can both bind to FPR2 and trigger superoxide release in neutrophils at low nanomolar concentrations. In addition, at high nanomolar concentrations they display cytotoxicity selectively on apoptotic neutrophil membranes and this occurs in an FPR2 independent manner.</p>

<p>BCL6 encodes a transcription factor that represses genes necessary for the terminal differentiation of lymphocytes within germinal centers, and the misregulated expression of this factor is strongly implicated in several types of B cell lymphoma. The homodimeric BTB domain of BCL6 (also known as the POZ domain) is required for the repression activity of the protein and interacts directly with the SMRT and N-CoR corepressors that are found within large multiprotein histone deacetylase-containing complexes.</p>

<p>ARF peptide, is the alternative frame (ARF) tumour suppressor protein which is expressed on the occurrence of oncogenic stimuli. It functions to prevent abnormal cell proliferation through inhibiting the p53 ubiquitin ligase protein Mdm2 from degrading p53. This results in the increased stability of the p53 tumour suppressor causing G1 cell cycle arrest. Additionally mouse ARF proteins can localise E2F1 and c-Myc transcriptions factors to the nucleolus therefore they are no longer able to activate S-phase promoting target gene. Again this results in cell cycle arrest, ultimately preventing tumour cell growth. It is evident that if the expression of the ARF peptide is inhibited tumour formation is more likely to occur.</p>

<p>Fragment of the angiotensin-converting enzyme 2 (ACE2) peptidase domain (PD) alpha1 helix, a domain important for the interaction of ACE2 with the severe acute respiratory syndrome (SARS coronavirus receptor binding domain (SARS-CoV-2-RBD). SBP1 associates with the SARS-CoV-2-RBD with nanomolar affinity and can potentially block the key mechanism by which SARS CoV-2 initiates entry into human cells.This peptide has a covalently bonded N-terminal Biotin tag that can be used for detection and purification and contains a polyethylene glycol spacer (PEG4).</p>

<p>Portion of EBV</p>

<p>Shepherdin is an antagonist of the interaction between the apoptosis protein, survivin, and the molecular chaperone, heat shock protein 90 (Hsp90). The sequence of shepherdin corresponds to the site where Hsp90 binds to survivin. Shepherdin therefore has high affinity for Hsp90 and thus disrupts survivin binding and acts as an inhibitor of Hsp90 ATPase function by competing with ATP.The survivin-Hsp90 complex is a regulator of cell proliferation and cell viability in cancer tissue. Shepherdin has anti-cancer properties and can significantly suppress the growth of lung cancer cell lines and acute myeloid leukaemia (AML) by inducing apoptosis.</p>

<p>Mastoparan is a 14-residue cationic peptide toxin isolated from the wasp Vespula lewisii venom which shows an important potency as an antimicrobial and anticancer agent but also as a Cell Permeable Peptide.<br>Mastoparan is mainly known to be a receptor-independant and allosteric regulator of G-protein by stimulating GTPase activity.<br>Besides modulating the activity of G-protein, Mastoparan have the ability to bind other intracellular targets such as Ca2+-ATP (implicated in Ca2+ release), small GTP binding proteins rho and rac, and many others.<br>Mastoparan also belongs to the cell permeable peptide (CPP) family. As such, Mastoparan increases the membrane conductance and permeability of planar lipid bilayer and liposomal membranes which leads to enhanced the penetration of Ca2+, Na+ or K+ ions.<br>Mastoparan have also a potential antibiotic effect due to its potent antimicrobial activity which can turn Mastoparan to a potential drug for infectious diseases.<br>Some studies have also reported that Mastoparan exhibits potent anti-cancer activities toward leukemia, myeloma, and breast cancer cells with an approximately half maximal inhibitory concentration (IC50) of 9µM, 11µM and 22µM respectively.<br>Mastoparan have shown to be more specific to cancer cells than to normal cells.</p>

<p>Alyerserin-1b is a C-terminally α-amidated 23 residue Cationic anti-microbial peptide (AMP). Anti-microbial peptides (AMPs) are produced by the innate immune system and are expressed when the host is challenged by a pathogen. The Alyerserin family of peptides was first identified in norepinephrine-stimulated skin secretions of the midwife toad-Alytes obstetricans-(Alytidae). Alyteserin-1 peptides have limited structural similarity to the ascaphins from the skins of frogs of the Leiopelmatidae family. Alyteserin-1 peptides are selective at inhibiting growth activity of Gram-negative bacteria-such as Escherichia coli and show weak haemolytic activity against human erythrocytes.Alyteserin contain at least 50% hydrophobic amino acids. Hydrophobic residues contribute to the insertion of the peptide into the hydrophobic membrane core which results in membrane disruption and death of the pathogen. Due to their mechanism of action it is less likely for resistance to develop towards them compared to conventional antibiotics.</p>

<p>PAF26 is a cell penetrating antimicrobial peptide (CP-AMP) with strong activity against fungi that cause postharvest decay in fruits, such as strains of Penicillium italicum, Penicillium digitatum, and Botrytis cinerea and is also active against Fusarium oxysporum.PAF26 has reduced toxicity to Escherichia coli and Saccharomyces cerevisiae, demonstrating selectivity towards certain filamentous fungi. PAF26 is endocytically internalized at low fungicidal concentrations and accumulates in vacuoles before being actively transported into the cytoplasm where it exerts its antifungal activity. PAF26 is not lytic or cytotoxic to human cells.</p>

<p>Histone 3 (H3) is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Both H4 and H3 are highly conserved and perform roles in binding to segments of DNA which enter and leave the nucleosome and in chromatin formation. Similar to the other core histone, H3 has a globular domain and a flexible N-terminal domain, 'histone tail' which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.The lysine at position 4 of this peptide has been tri-methylated and it is implicated in studies that this modification may remodel the chromatin so that it is more accessible to transcription factors, which may ultimately increase the level of gene expression. The lysine at position 9 has been acetylated, which neutralizes the positive charge on the amino acid, loosening the chromatin structure. This alteration to the accessibility of chromatin promotes the initiation of transcription. Moreover, the serine at position 10 has been phosphorylated, and studies have suggested that this may induce chromatin condensation, and subsequently repress transcription and gene expression.This peptide contains a C-terminal GGK linker labelled with 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag. This peptide also has an uncharged C-terminal amide.</p>

<p>Histone 4 (H4) is one of the four core histones (H2A, H2B, H3 and H4) which are essential for compacting eukaryotic DNA into the nucleosome. Due to the high lysine and arginine content, histones have a net positive charge and therefore electrostatically interact with negatively charged DNA. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Like other core histones, H4 has a globular domain and a flexible N-terminal domain, the histone tail, which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination.Gene transcriptional activation or inactivation is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes. Both processes function to alter the positioning of the nucleosome, allowing the DNA within to be either accessible to the transcription machinery or inaccessible. H4 lysine rich tail plays a role in the higher order chromatin folding.The lysines at positions 5, 8, 12 and 16 have been acetylated, which neutralizes the positive charge on the amino acid, loosening the chromatin structure. This alteration to the accessibility of chromatin promotes the initiation of transcription. Acetyl-Histone H4 (1-21) K5Ac, K8Ac, K12Ac, K16Ac-GG-[Lys(5-FAM)]-has a C-terminal GGK linker labelled with 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag. Additionally, this peptide has an uncharged C-terminal amide and is protected from N-terminal modifications by a covalently bonded acetyl group.</p>

<p>ANP (7-20) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in the cardiovascular remodelling process.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in proANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.</p>

<p>TAT-GSK'364A peptide is able to specifically mimic the binding sequence between Midline-1 (MID1) and the protein phosphatase 2A (PP2A) alpha4 complex and therefore can specifically outcompete MID1 from binding to alpha4-PP2Ac. TAT-GSK'364A therefore is useful in studying Alzheimer's disease (AD). AD is characterized by senile plaques, composed of amyloid-β (Aβ) peptides, derived from sequential proteolytic cleavage of the amyloid precursor protein (APP), and neurofibrillary tangles, composed of hyperphosphorylated tau protein.MID1 protein induces the translation of amyloid precursor protein (APP) mRNA via mTOR-eIF signalling and binds to PP2A to form the MID1-PP2A complex. PP2A is the main tau phosphatase and MID1 is a negative regulator of PP2A activity as it acts as an E3 ubiquitin ligase to promote the ubiquitin-dependent degradation of PP2A.GSK'364A contains 29-residue sequence from the alpha4 subunit (AQAKVFGAGYPSLPTMTVSDWYEQHRKYG) with an N-terminal sequence derived from HIV-TAT protein (RKKRRQRRR).</p>

<p>Galanin (mouse, rat) is 29 amino acids, 1 less than human galanin. Galanin is a widely distributed neuropeptide in the central nervous, peripheral, and endocrine systems. Galanin interacts with 3 receptor subtypes, GalR1-3. These G protein-coupled receptors are inserted into the plasma membrane. Galanin has a role in energy homeostasis. Central injections of galanin to the amygdala lead to food intake in rats.Galanin has been shown to inhibit glutamate release from the hippocampus. Glutamate has an excitatory effect in the mechanisms of epileptic seizures- therefore, galanin is considered a possible anticonvulsant.  Galanin receptor agonists with anticonvulsant properties have been developed to help seizures. Galanin has also helped provide evidence of neuronal plasticity and degradation. Galanin has been used extensively for administration to animals in vivo including rats and mice to better understand its role and help treat appetite disorders.</p>

<p>Selective peptide ligand for FRalpha, demonstrating specific binding to FRalpha expression cells and tumour targeting ability in vivo. It contains 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.</p>

<p>Tumour antigens recognised by cytotoxic T cells (CTLs) are a keen area of research to develop antigen-specific cancer therapies. However, hurdles are weak immunogenicity and high rates of degradation in vivo. In the search for a melanoma vaccine, the human tumour antigen Melan-A/MART-1 (27-35) has been used as a model to design peptides with improved characteristics for use in anti-tumour vaccines. The MART-1 fragment provided here has an alanine substituted at position one from MART-1 (27-35) this is a natural variant of MART-1 found in the population. Melan-A specific CTL assays showed this MART-1 fragment A27L to be a superagonist with higher affinity than the parent peptide. Also, the MART-1 fragment is a more stable complex with HLA-A*0201 than the parent peptide as determined by degradation experiments using a functional cytolytic assay. The superagonist activity of the MART-1 fragment and the stability of the peptide may be a considerable step towards an anti-melanoma vaccine.</p>

<p>Cilengitide is a cyclic arginine-glycine-aspartic acid (RGD) motif containing peptide that selectively inhibits the integrin alphav subunit. Integrins are cell adhesion molecules which mediate cell-cell and cell-matrix interactions and creating a scaffold for tissue organisation. Integrins also act to regulate cell attachment, proliferation, differentiation, apoptosis and motility.Integrin alphav can form heterodimers with integrin subunits subunits β1, β3, β5, β6, or β8. Cilengitide is a highly specific antagonist of alphavβ3 and alphavβ5 integrins. It also and shows anti-angiogenic effects and inhibits growth and promotes apoptosis of tumour cells that express integrins, such as glioblastoma.Cilengitide has gone on to phase II trials for cancers such as glioblastoma, melanoma, prostate, breast, lung and head and neck cancers.</p>

<p>C-peptide is a peptide hormone that is cleaved from proinsulin in the pancreatic beta cells. Both C-peptide and insulin are released by the beta cells in the event of glycaemia. Due to it having a relatively long half life, compared to insulin, and the fact it is not immediately metabolised by the liver, makes C-peptide a useful biomarker to monitor beta cell function. Increased levels of C-peptide occurring in patients with insulin resistant type 2 diabetes mellitus, have been associated with macrovascular complications and cardiovascular morbidity. During in vitro studies it has also been found that C-peptide prevents endothelial cell reactive oxygen species from being formed and therefore oxidative stress is reduced. This also may lead to anti-inflammatory and anti-apoptotic responses.</p>

<p>As an antimicrobial peptide (AMP), IDR-1 acts indirectly on pathogenic bacterial infections. IDR-1 is proposed to function by upregulating monocyte cytokines (interleukins) while also reducing a pro-inflammatory cytokine. IDR-1 has been tested for its ability to aid against the rise of multi-drug resistant bacteria. In mouse models, IDR-1 is protective against Gram-positive and Gram-negative pathogens. Supply of IDR-1 can also attenuate methicillin-resistant staphylococcus aureus (MRSA)-induced pneumonia. The IDR-1 sequence is being studied as a template to hopefully generate more potent synthetic versions.</p>

<p>Connexin43 mimetic peptide which can reduce swelling, astrogliosis, neuroinflammation and neuronal cell death following spinal cord injury ex vivo and in vivo. Reduces mechanical pain hypersensitivity by specifically targeting the NLRP3 inflammasome in the spinal cord. Possesses analgesic effects in mouse neuropathic pain models.</p>

<p>Affinity chromatography and protein purification are more successful with highly selective ligands such as short peptides. Phage libraries have been utilised to identify novel peptides for target proteins. IgG1 monoclonal antibody is traditionally purified using protein A but is not ideal due to cost and methodology. EPIHRSTLTALL was found via phage library screening as the most selective ligand possible IgG1, and also highly stable. It binds to the constant region of IgG1 known as humanized anti-Tac (HAT). HAT is a humanized monoclonal antibody against the low-affinity p55 subunit of the interleukin IL-2 receptor.</p>

<p>Amino acids 1-24 of human adrenocorticotropic hormone (ACTH), induces glucocorticoid production by adrenal cells with the same potency as full length ACTH. ACTH, also known as corticotropin, is a tropic hormone produced and secreted by the anterior pituitary gland and member of the melanocortins peptide family. ACTH is cleaved from the precursor proopiomelanocortin (POMC). ACTH is an important component of the hypothalamic-pituitary-adrenal (HPA) axis and is often produced in response to biological stress. ACTH acts to increase the production and release of cortisol via its interaction with the ACTH receptor- ACTHR, also known as melanocortin type 2 receptor (MC2R). Receptor activation increases the intracellular concentration of cAMP via adenylyl cyclase.Abnormal ACTH levels in the body has been linked to primary adrenal insufficiency/Addison's disease, Cushing's disease and secondary adrenal insufficiency.</p>

<p>Galanin is a neuropeptide synthesised and released by the brainstem locus coeruleus (LC). Galanin is expressed in most LC neurons in rodents and humans. Galanin has been shown to inhibit LC activity by hyperpolarising LC neurons, suppressing their spontaneous firing rate, and enhancing alpha2-adrenergic receptor-mediated negative feedback. Galanin is also a potent trophic and neuroprotective factor throughout the nervous system.Galanin is widely distributed in the central nervous, peripheral, and endocrine systems. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes, GalR1-3, which are G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the Galphai/o pathway. Activation of the receptor leads to a cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.N-terminal fragments are naturally occurring in vivo but their relevance is not clear. Some N-terminal fragments reduce metabolic and functional disorders in experimental heart damage. Using N-terminal fragments such as galanin (3-13) can clarify the function of full-length galanin during myocardial ischemia and reperfusion injury. This may highlight new agonists/antagonists for the galanin GalR receptors that can be putative therapeutic targets.A C-terminal biotin tag for easy detection and purification has been added to the galanin (3-13) fragment.
