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>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>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>C5a receptor 2 (C5aR2, or C5L2) is a seven transmembrane non-G-protein-signalling receptor which binds the complement activation peptide C5a ligand. The complement cascade is a highly sophisticated network of innate immune proteins that are activated in response to invading pathogens or tissue injury. C5aR2 regulates the release of certain cytokines and is involved in a number of inflammatory conditions. C5aR2 can recruit and form a complex with β-arrestins, which can modulate ERK1/2 signalling in macrophages and neutrophils. C5aR2 has both pro- and anti-inflammatory actions. P32 is a functionally selective C5aR2 ligand which is able to recruit β-arrestin 2 with high efficacy, inhibit C5a-induced ERK1/2 activation and can selectively inhibit LPS-induced IL-6 release from human monocyte-derived macrophages (HMDMs). Functionally selective ligands for C5aR2 such as this are novel tools that can selectively modulate C5a activity and are therefore valuable tools in investigating C5aR2 function.</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>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>

Pan HLA DR-binding epitope can be also used as tool to study the autoreactive T cell response.

<p>Bacterial cell invasion begins by initially adhering to mucosa of the oro-intestinal, nasorespiratory, or genitourinary tract by specific adhesins. This leads to colonization of the region and ultimately infection. Studies showed acetyl-adhesin can inhibit binding of S. mutans to salivary receptors and can prevent S. mutans colonising the teeth. This suggests the peptide may be a useful antimicrobial agent against bacterial mucosal colonisation, particularly tooth decay.</p>

<p>Acetly-Claudin-9 is derived from the tight junction protein Claudin-9 which is encoded by the CLDN6 gene and can be found within epithelial cell to cell contacts. Structurally, the Claudin family, of which Claudin-9 is a member, are transmembrane proteins containing two extracellular loops and are involved in maintaining cell polarity and controlling paracellular ion flux.Reduction in the number of Claudins has been associated with tumour formation. This may be due to Claudin role in maintaining cell detachment and migration.Claudin-9 has been shown to be overexpressed in hepatocellular carcinoma (HCC) and has the ability to increase the metastasis of hepatocytes. It further influences the activation of the Stat3 signalling pathway through tyrosine kinase 2. Overall CLDN9 demonstrates itself to be a HCC proto-oncogene.</p>

<p>Jelleines are a family of very small (8-9 amino acid residues long) host defence peptides (HDPs) isolated from the royal jelly of honey bees (Apis mellifera). Jelleines do not present any similarity with other HDPs from other honeybees and are produced by the workers and secreted into Royal Jelly (RJ), providing abroad-spectrum protection of the bee hive against microbial infections. The Jelleines are not considered cytolytic or directly involved with inflammatory effects. Jelleine-II may be a product of a tryptic digestion of MRJP-1, which is produced in the hypopharyngeal glands of the worker honeybee and secreted into the RJ- an exoproteinase action either on N-or on C-terminal positions of the tryptic fragment could result in the formation of the Jelleines-I and -IV, respectively. Possess antimicrobial properties against yeast, fungi, gram-positive and gram-negative bacteria.PLEASE NOTE that in several published articles the sequence of Jelleine-2 has been printed as TPFKISLHL-NH2-NH2, due to a mistake in the original reference: Fontana et al., (2004). The correct sequence, is TPFKISIHL-NH2.</p>

<p>This peptide represents the anti-microbial domain of the LL-37 peptide. LL-37 is a member of the large cationic family of anti-microbial peptides called cathelicidins which have broad-spectrum anti-microbial activity and are expressed in many species. The only cathelicidin found in humans is LL-37- this is produced in epithelial cells, by proteolytic cleavage from the C-terminal of the hCAP-18 protein. LL-37 can be processed into different forms of anti-microbial peptides. As well as its anti-microbial properties LL-37 also has anti-cancer properties and regulates many aspects of the innate immune system, overexpression of LL-37 has been linked to autoimmune diseases such as asthma and psoriasis.</p>

<p>Orexin A is one of two closely related peptides- the orexins (also known as hypocretins). These small neuropeptides are secreted from orexin-containing neurons, located mainly in the lateral hypothalamus (LH). Orexins function via the binding and activation of two G-protein-coupled receptors (GPCRs)- orexin receptor type 1 (OX1R) and 2 (OX2R).Orexins play several vital roles in a range of physiological activities, including: circadian rhythm, feeding behaviour, energy balance, glucose metabolism, neuroendocrine functions, stress-adaptive responses and reward and addiction. Orexins have also been linked to the pathological processes of neurological diseases such as: narcolepsy- depression- ischemic stroke- drug addiction and Alzheimer's disease.This Orexin A peptide contains two disulphide bridges, one between cysteine 7 and cysteine 13, and the other between cysteine 8 and 15. Orexin-A appears to be the isoform most important for the feeding response.</p>

<p>This peptide is phosphorylated by Janus kinase 2 and 3 (JAK2 and JAK3) and is an ideal substrate for use in kinase assays. The JAK family of kinases is essential for the signalling of a host of immune modulators in tumour, stromal, and immune cells where they are highly expressed. JAK family proteins mediate the signalling of the interferon (IFN), IL-6, and IL-2 families of cytokines.JAK kinases are associated with cytokine receptors. Cytokine binding to these receptors results in activation of JAK kinases and receptor phosphorylation. Phosphorylated cytokine receptors recruit STAT proteins, which are then phosphorylated by the activated JAK kinases. Phosphorylated STAT proteins form homo- and hetero-dimers that translocate into the nucleus and function as transcription factors.This peptide contains an N-terminal biotin tag for easy detection and purification.</p>

<p>ANP (9-22) 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>The cyclic tridecapeptide Compstatin, binds to and selectively inhibits the interaction between C3 and convertase, hence preventing the formation of C3a and C3b and activation of the complement system. Compstatin has the ability to form β-turns and hydrophobic clusters which are crucial for its inhibitory properties. When binding between C3 MG4 and MG5 domains, located within the MG-ring of the β-chain, Compstatin undergos a conformational change which is believed to prevent C3 from binding to C3 convertase through steric hindrance. Consequently the complement cascade is inhibited.The complement cascade is an important feature of the immune system. C3b, produced from the interaction of C3 and C3 convertase, binds to pathogens and somatic cells and signals for their removal from the body. However the increased activation of the complement system can result in diseases, associated with Alzheimers, strokes, heart attacks and autoimmune diseases. Therefore Compstatin can be used as a therapeutic agent within medicine.</p>

<p>Neuropeptide S (NPS) is a neuropeptide found in mammalian brains, primarily in neurons in the lateral parabrachial nucleus, the peri-locus coeruleus and the principle sensory 5 nucleus of the trigeminus. NPS in involved in several neuroendocrine, behavioural and inflammatory responses, including: reducing anxiety in mice- suppressing appetite and inducing wakefulness and hyperactivity. NPS treatment can be used to improve fear extinction in mice and limit fear memory retrieval after fear reduction training, thus making it an interesting target for treatment of post-traumatic stress disorder. NPS exerts its actions by binding to a G-protein coupled receptor, NPSR.</p>

<p>Survivin is an intracellular tumour-associated antigen that is part of the inhibitor of apoptosis (IAP) family. Survivin expression increases as cells age but becomes over-expressed in cancer cells. Expression is also important during embryonic development and tissue regeneration. With roles in aging, apoptosis, and cancer, there is considerable interest in understanding the function of Survivin. Survivin expression is regulated by TGF-β and increased following intestinal inflammation during the healing process.The high expression of Survivin in cancer cells has led to the search for a vaccine that induces epitope-specific CD8+ T cells. The epitope TFKNWPFL restricted to H-2 Db was identified using prediction algorithms and MHC class I binding assays. The epitope was delivered to mice by intradermal electroporation (EP). The Survivin epitope induced a  CD8+ cytotoxic T lymphocyte (CTL) response as shown by IFN-staining- they also showed an activated effector phenotype as CD44 and CD107 were upregulated. The Survivin vaccine was able to confer protection against melanoma in mice and suppress angiogenesis. This Survivin epitope could be a vital step in creating a human vaccine that generates CD8 CTLs with specific functional cytotoxic activity against tumour cells.The sequence provided here aligns to residues 21-28 of the Survivin epitope, the initial residue of the epitope has been omitted as it is not conserved between mice and human sequences.</p>

<p>The coronavirus (CoV) nucleoprotein is the major component of CoV structural proteins. Also known as the nucleocapsid protein, it is an abundant RNA-binding protein critical for viral genome packaging. These factors make nucleoprotein a good target for developing new antiviral drugs. In addition, the identification of epitopes within the nucleoprotein sequence can help design more effective SARS-CoV-2 vaccines.Models have predicted epitopes exhibiting antigenicity, stability and interactions with MHC class-I and class-II molecules. Nucleoprotein (261-275) is an epitope candidate with various HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.</p>

<p>Galanin is predominantly an inhibitory neuropeptide expressed in humans and other mammals' brains, spinal cords, and gut. Galanin signalling occurs through three G protein-coupled receptors GalR1-3. Galanin has been implicated in many biologically diverse functions, including nociception, waking and sleep regulation, cognition, feeding, mood regulation and blood pressure regulation. Galanin appears to have neuroprotective activity as its biosynthesis is increased 2-10 fold upon axotomy and during seizure activity in peripheral tissues and the brain.The clinical relevance of galanin is related to several chronic neural disorders, including Alzheimer's disease, epilepsy, depression and cancer- those who suffer from type 2 diabetes mellitus, depression and Alzheimer's disease often express high levels of galanin. Conversely, intervention with galanin agonists (for example, M617, M1145 and M1153) were able to ameliorate disease symptoms such as Alzheimer's and have pro-nociceptive effects. Specifically, activation of GAL2 can alleviate such disease features in human and rodent models. This galanin (2-30) peptide has been used to characterise Galanin's binding sites and affinity for GALR receptors via competition binding analysis. Galanin (2-30) is a full agonist of the GALR2 receptor compared to its affinity for GALR1.</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 trials 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 (396-405), has been shown to provide absolute quantification of dystrophin levels from biopsies using parallel reaction monitoring. This will hopefully allow better management of dystrophin disorders with better quantifications tools based on dystrophin (396-405). 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>Nef is an accessory protein highly conserved amongst all primate lentiviruses, it is essential for viral replication in vivo- it is expressed by human immunodeficiency virus (HIV) HIV-1 and HIV-2. Nef acts as a downregulator of class I human leukocyte antigens (HLA) expression in HIV-infected cells to help circumvent the immune response, such as Cytotoxic T lymphocytes (CTL) activity. An intact nef gene is critical for high viral loads, linked to development of acquired immunodeficiency syndrome (AIDS). Certain alleles of HLA have been associated with maintaining a seronegative status such as HLA-A*1101.This nef peptide sequence contains the region considered to be a a C-proximal adaptor-protein (AP) interaction site. The presence of various nef motifs such as this are an intense area of investigation to understand if they are a factor in patients who remain clinically asymptomatic. This nef fragment is provided with an N-terminal acetyl group to increase its stability.</p>

<p>Fmoc-D-Ile-OH is a peptide that inhibits the activation of protein interactions. It is also used as a research tool to study the binding of ligands to receptors. Fmoc-D-Ile-OH has been shown to bind to ion channels, such as nicotinic acetylcholine receptor and voltage gated potassium channels. This inhibitor has also been shown to bind with high affinity to a receptor with unknown identity.</p>

<p>Apelin (65-76), human is derived from the apelin peptide which acts as a ligand for the apelin receptor (APJ) G protein coupled receptor and is a substrate for angiotensin converting enzyme 2. Preprapelin, encoded for by APLN located on Xq25-26.1, is cleaved to form either apelin 36 or apelin 17, 12 and 13. As a member of the adipokine hormone family, which are involved in processes such as vascular homeostasis and angiogenesis, the apelin is secreted from adipose tissue.Apelin has been found to be expressed in the spinal cord and the human brain and when performing immunohistochemistry it was observed that apelin-17 is significantly expressed in the human heart, brain, lungs and endothelial cells.Both apelin and the apelin receptor are widely distributed around the body thus apelin has been found to be associated with cardiovascular diseases, obesity, diabetes and cancer. Studies exploring myocardial infarction showed there to be greater apelin mRNA expression during human heart failure compared to in healthy tissue. Apelin protects against heart failure due to, the pyroglutamyl form of apelin, playing a role in decreasing infarct size of myocardial infarctions. Furthermore in rats with hypertension, the expression of apelin and APJ was decreased.</p>

<p>HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. New York oesophageal squamous cell carcinoma 1 (NY-ESO-1) is part of a well-characterized group of cancer/testis antigens (CTAs). Normally, NY-ESO-1 expression is restricted to germ cells and placental cells, however NY-ESO-1 is also expressed in several cancers including: neuroblastoma- myeloma- metastatic melanoma- synovial sarcoma as well as bladder- oesophageal- hepatocellular- head and neck- non-small cell lung- ovarian- prostate and breast cancers and is often associated with poor prognosis. NY-ESO-1 is also able to elicit a spontaneous immune response, being the most immunogenic among the CTA family members and is therefore the most promising CTA candidate target for cancer immunotherapy.NY-ESO-1 is coexpressed with melanoma antigen gene C1, a member of the MAGE family of CTAs which is involved in cell cycle progression and apoptosis.</p>

<p>Neurotensin (NT) is involved in food absorption in the gut as well as acting as a neurotransmitter in the central nervous system (CNS). In the intestine, NT increases fatty acid translocation, in part by increasing intestinal blood flow. In the CNS, NT regulates pathways associated with ghrelin and leptin which mediate satiety and food ingestion. NT is also involved in the regulation of Luteinizing hormone (LH) and Prolactin release and also plays a role in hypotension- analgesia- gut contraction- vascular permeability- maintaining energy homeostasis- fat storage and metabolic disorders. Higher plasma pro-NT levels are associated with obesity and insulin resistance. NT is therefore a potential target for treating obesity-related diseases.NT is secreted from neuroendocrine cells in the small intestine upon fat intake and exerts its physiological actions by binding three NT receptor (NTR) types- NTR1, NTR2, and NTR3.NTR1 is highly expressed in various tumour cells including- small cell carcinoma/small cell lung cancer (SCLC)- meningiomas- astrocytomas- glioblastoma- pancreatic and colonic carcinoma, and breast and prostate cancers. NTR1 is therefore a possible target for novel cancer therapy.</p>

<p>The histone H2A residues 1-20 are derived from histone 2A (H2A) which is one of the four core his-tones (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.At the site of DNA entry on the outer nucleosome, the C-terminus of H2A is present and is able to interact with linker histones or other factors. This allows for variation and changes in nucleosome stability to occur. Furthermore Histone H2A has histone variants such as H2A.Z and H2A.X (which are present in all organisms) and these variants alter the organisation of the DNA.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 to change the positioning of the nucleosome, allowing the DNA it to be either available to the transcription machinery or inaccessible.</p>

<p>Fluorescein labelled amyloid β 1-15 (Aβ1-15 ). Aβ1-15 is one of many short Aβ species found in vivo and is formed by the cleavage of Aβ precursor protein by β- and alpha-secretase.Amyloid β-protein (Aβ) 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.Fluorescein (FAM) is a hugely popular fluorescent tag due to its excellent fluorescence quantum yield and relatively high absorptivity as well as being highly water soluble.</p>

<p>Glucagon-like peptide (GLP) 1 is a post-translationally modified version of proglucagon. GLP-1 (1-37) is a naturally produced analog of GLP-1. Unlike truncated GLP-1, GLP-1 (1-37) does not alter food intake in rat models or pancreatic insulin secretion. GLP-1 (1-37) can induce insulin production in developing adult intestinal cells via upregulation of the ngn3 gene and its downstream targets. This can restore glucose homeostasis when implanted into diabetic mice. GLP-1 (1-37) may offer a  future treatment for diabetes mellitus. GLP-1 (1-37) can also inhibit chemokine-induced migration of human CD4-positive lymphocytes, an early step in atherogenesis. This raises the possibility that GLP-1 (1-37) is part of a novel mechanism to modulate vascular disease.</p>

<p>A hydroxyproline glycine peptide in acid form. This peptide is a substrate for prolyl dipeptidase. Ingestion of the Hyp-Gly dipeptide can improve skin conditions.

<p>There are three members of the p160 family of steroid receptor coactivators, SRC-1, SRC-2, and SRC-3. These steroid receptor coactivators control the functional output of numerous genetic programs and serve as pleiotropic rheostats for diverse physiological processes. Coactivator proteins interact with nuclear receptors in a ligand-dependent manner and augment transcription.This peptide contains a covalently bonded N-terminal Biotin tag that can be used for detection and purification.</p>

<p>Ghrelin is involved in several physiological processes, including feeding and lipid accumulation, stress response, anxiety, cardiac performance, immunity and inflammation, taste sensation, reward-seeking behaviour, regulation of glucose metabolism and thermogenesis, memory, motivation and learning.Ghrelin is a peptide hormone that typically has a serine at the third residue and relies on modification with a fatty acid to give ghrelin its functional activity. In its modified form, ghrelin is an endogenous ligand for the pituitary gland's growth hormone receptor (GHS-R) and stimulates growth hormone release. Rat/mouse ghrelin differs from the human form at positions 11 and 12 (RV) in rats to (KA) in humans.Ghrelin acts on the hypothalamic arcuate nucleus as an orexigenic agent to stimulate appetite. Ghrelin is produced in the stomach as a precursor peptide preproghrelin, cleaved to ghrelin. Ghrelin circulates in the blood and can cross the blood-brain barrier. Levels of ghrelin respond to fasting conditions and allow signals about the energy status to be transmitted from the peripheral organs to the central nervous system to maintain energy homeostasis.Ghrelin is a valuable target for treating conditions such as anorexia, cachexia, sarcopenia, cardiopathy, neurodegenerative disorders, renal and pulmonary disease, gastrointestinal disorders, inflammatory disorders and metabolic syndrome.</p>

<p>Transportan is an amphipathic 27 amino acid peptide that was generated from 12 functional amino acids of galanin and 14 amino acids of mastoparan connected via a lysine residue. Transportan has been functionally characterised as a cell penetrating peptide (CPP) that does not appear to be mediated by endocytosis. All cell types tested were permeated by transportan, initially localising to the outer membrane it then travels to cytoplasmic membrane structures and eventually perfuses to the nucleoli. This CPP has been used for numerous applications and assays to great effect including indirect immunofluorescence and drug delivery.TP reveals some characteristic features of both galanin and mastoparan since it inhibits the binding of galanin to GALR-1 receptor as well as modulates the activity of G proteins due to the inhibition of GTPase activity.</p>
