This 32 amino acid peptide contains a 17 amino acid ring structure that is common to all natriuretic peptides. It is also called the brain natriuretic peptide (BNP) because it was first identified in porcine brain- however, the main source of this peptide is not the brain but the cardiac ventricle. This cardiac neurohormone is secreted from the ventricles in response to volume expansion and pressure overload. It has natriuretic and vasodilatory effects and suppresses the renin-angiotensin-aldosterone system.

Reactivity to human leukocyte antigens (HLAs) is a rising concern in clinical treatments such as organ transplant rejection. Understanding the epitopes and the signalling pathways leading to reactivity could produce better clinical therapies in the future. The peptides presented by the non-classical HLA-G are important for a largely tolerogenic role and are considered part of an immune checkpoint. This, therefore, makes understanding ligand characteristics and HLA-G a target for cancer therapies. Interleukin-27 subunit β (22-30) fragment has been identified as an epitope that human leukocyte antigen HLA-G naturally presents, determined by liquid chromatographic tandem mass spectrometry (LC-MS/MS). This epitope has been used extensively in the literature to help understand the natural ligand presentation of HLA-G.For example, leukocyte immunoglobulin (Ig)-like receptors (LILRs) are key regulators of the immune response and therefore targets for therapeutics. Inhibitory LILRB1 and LILRB2 with HLA-G are pivotal for immunotolerance during pregnancy and autoimmune diseases plus cancer cell immune evasion. Interleukin-27 subunit β (22-30) fragment was used in binding affinity assays to clarify the conformational plasticity of the interaction between the receptor, the HLA antigen, and the various peptides HLA-G can accommodate.

JAG-1(188-204). Jagged - 1 is a cell surface ligand for in the Notch pathway. Notch receptors and ligands are present on the extracellular service of cells and require cell-cell contact for engagement. Ligand binding to Notch receptors results in the proteolytic cleavage of membrane-bound Notch receptors, thus allowing the intercellular region to be transported to the nucleus and become a transcriptional activator. The ligand-induced Notch activation is regulated by E3 ubiquitin ligases, Mindbomb1 (Mib-1) and Neuralized.JAG1 is widely expressed throughout mammalian development, across many tissues and developmental stages. Notch signalling plays a critical role in cellular fate determination including muscle cell differentiation, neurogenesis, and the development of the sensory regions of the inner ear- heart- kidney- eye- lung and other tissues.Jag-1 has been implicated in breast- cervical- colorectal- endometrial- gastric- head and neck- ovarian- hepatocellular- lung- pancreatic- prostate, and kidney and adrenocortical cancers, leukemia and lymphoma. Co-overexpression of Notch-1 and Jagged-1 predicts the poorest overall cancer survival. JAG1 mutations have also been associated Alagille syndrome.

Des-n-Octanoyl-[Ser3]-Ghrelin (Human) is a peptide that belongs to the class of GHSR ligands. It is used in research for its ability to activate the ghrelin receptor, which is found on cells in the stomach lining and central nervous system. The binding of ghrelin to this receptor stimulates the release of growth hormone from the pituitary gland and increases appetite. This product can be used as a research tool for identifying new ligands for the ghrelin receptor or for pharmacology studies on other GHSR receptors. This peptide has been shown to inhibit ion channels, such as those found in pancreatic beta cells, that are involved in insulin secretion.

Amino acids 1-18 of the 28 amino acid peptide hormone Ghrelin which has various effects on the body, including stimulating appetite, nutrient sensing and meal initiation. It has also been found to regulate insulin resistance, diabetes and obesity and asserts its functional affects through acting as an endogenous ligand for the growth hormone secretagogue receptor (GHS-R). Ghrelin is able to associate with the GHS-R due to it containing a unique N-octanoyl group which is linked to its serine 3 residue covalently. Its wider functions such as glucose homeostasis, energy homeostasis, cardio-protective effects, its role in bone metabolism and its potential to be a target for cancer means that it can be used to develop therapies for a whole spectrum of diseases.

Galanin is a widely distributed neuropeptide in the central nervous system (CNS), peripheral regions and endocrine system. Galanin interacts with 3 receptor subtypes, GalR1-3 G protein-coupled receptors inserted into the plasma membrane. Galanin has a role in energy homeostasis. Central injections of galanin to the amygdala led to food intake in rats. Galanin also acts in the CNS to inhibit neurotransmitter release, such as acetylcholine. Galanin has been implicated in numerous neurological conditions, including Alzheimer's disease, depression, and epilepsy. A better understanding of the galinergic signalling pathways may uncover a source for therapeutics for conditions such as epilepsy.Unlike human galanin, full-length porcine galanin contains only 29 amino acids and is C-terminally amidated. The first 15 residues are still highly conserved.  The best-recognized effect of galanin on the endocrine pancreas is the inhibition of insulin secretion in vitro and in vivo on multiple model systems, including rats, dogs, and mice. However, the same effect cannot be achieved at the same concentrations in human models with infusions of porcine galanin. Structural activity and point mutation studies show that the N-terminal (1-15) fragment is vital for the interaction/activation of the GAL receptor and the inhibition of insulin secretion.

Acetylated α-synuclein (1-7) amide is derived from the alpha-synuclein intrinsically disordered protein which is found in the neurons and presynaptic terminals. Encoded by the SNCA1/PARK1 gene alpha-synclein is structurally composed of 140 amino acids, making up the three domains: N-terminal membrane binding domain, a hydrophobic non-amyloid-β component domain and a hydrophilic C-terminal domain. Usually alpha-synuclein plays a role in protecting neurons from apoptotic stimuli and is involved in synaptic vesical trafficking.However it has been found that the accumulation of alpha-synuclein aggregates can lead to neurodegenerative diseases such as Parkinson disease, dementia with Lewy bodies and multiple system atrophy. It is further involved in the fibrilisation of amyloid-b and tau which play a major role in Alzheimer disease. Amyloid fibrils are formed from alpha synuclein monomers within the cytosol and when bound to membranes these monomers can undergo conformational changes to form protofibrils and then ring like oligomers. This can result in the formation of transmembrane pores which disrupts the membrane, calcium homeostasis and signalling.Alpha-synuclein can be subjected to the post-translational modifications of phosphorylation and N-terminal acetylation. When acetylation occurs at the N-terminus of an alpha-synuclein monomer, the intramolecular hydrogen bonds are altered thus reducing the rate of alpha-synuclein aggregation and the strength at which it interacts with the membrane is increased.

Proinsulin connecting peptide (C-peptide), links the A and B chains of proinsulin. Upon enzymatic cleavage of C-peptide from pro-insulin in the pancreas, C-peptide is released into the blood stream along with insulin (A- and B-chains bonded together) in equimolar quantities. C-peptide can influence a wide variety of physiological conditions linked to diabetes, such as neuropathy, nephropathy, and encephalopathy. C-peptide is able to ameliorate and reverse the degrading effects of neuropathy in diabetes.
