An immuno-receptor tyrosine-based activation motif (ITAM) is a phosphorylation site consisting of a conserved sequence of four amino acids that is repeated twice in the cytoplasmic tails of cell-surface non-catalytic tyrosine-phosphorylated receptors. ITAMs are involved activation of immune cells. The motif has the following structure: YxxL/I. where xx are any two amino acids. Two of these motifs are typically separated by between 6 and 8 amino acids in the cytoplasmic tail of the molecule (YxxL/Ix(6-8)YxxL/I). ITAMs are found in the CD3 and θ¶-chains of the T cell receptor (TCR) complex. TCR is a multi-subunit receptor on the surface of T cells which contains two ligand binding chains containing 20 phosphorylation sites, distributed on 10 ITAMs. The TCR θ¶-chain is a homodimer subunit that contains six ITAMs (12 sites). These sites are phosphorylated by the membrane-anchored Src family tyrosine kinase Lck and Fyn and are dephosphorylated by the transmembrane phosphatases CD148 and CD45. When both tyrosines in an ITAM are phosphorylated they generate docking sites for the tandem SH2 domains of the cytosolic tyrosine kinase ZAP-70. Bound ZAP-70 can phosphorylate tyrosines on other substrates that initiate the signal transduction that leads to T cell activation. The multiple ITAMs on the TCR function mainly to amplify subsequent signalling.T cells rely on the TCR to recognize antigens, in the form of peptides bound to major histocompatibility complexes (MHC), on the surfaces of antigen-presenting cells. Binding of TCR to antigen-MCH complexes leads to proliferation, differentiation, and the secretion of effector cytokines, contributing to the elimination of infections.

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.

Suc-Ala-Glu-Pro-Phe-pNA is a peptide that is a specific interaction with neutrophils. It is an endogenous factor that has been shown to activate neutrophil functions, such as chemotaxis and phagocytosis. The substrate proteins of this peptide are involved in the regulation of neutrophil functions. Suc-Ala-Glu-Pro-Phe-pNA has also been shown to inhibit the activity of phosphatases, which may lead to inhibition of cell proliferation. The structure activity relationship studies for this peptide show that it can be used as an inhibitor for cells in early stages of development.

This peptide constitutes the acetylated N-terminal region of murine myelin basic protein (MBP) and displays high affinity for major histocompatibility complexes (MHC). This high MHC affinity is due to substitution of the native lysine at position 4 for a tyrosine. Substitution increases the MHC binding affinity of the peptide by around 1 million fold, therefore creating a superagonist ligand. MBP is an integral component of myelin found in the central nervous system (CNS) vital for the development and stability of the myelin sheath where it plays a role in membrane adhesion. MBP may be targeted by auto-antibodies in diseases such as multiple sclerosis. The low affinity of the native lysine containing MBP 1-9 peptide for MCH class II may result in MBP auto-reactive T cells escaping central-tolerance where self reactive T cells are usually eliminated. MBPs constitute an extraordinarily varied collection of splice isoforms which show a myriad of post-translational modifications.

Locustatachykinin I(LTK1 or Lom-TK-I) is a potent, rapid and persistent secretion stimulator in locust Malphigian tubules which controls primary urine production, tubule writhing and local sphincter functions.- LTK1 shares sequence homology with mammalian tachykinins such as substance P.- Two putative tachykinin receptors, Drosophila tachykinin-receptor (DTKR) and neurokinin receptor from Drosophila (NK0) have been identified.

H-Tyr-Arg-Leu-Leu-Ser-Phe-NH2 is a peptide that is used as a research tool for studying the role of PAR receptors in the regulation of vascular tone. It also has been shown to have an effect on blood pressure, which may be due to its ability to activate PAR2 receptors.

[5-FAM]-TAT (47-57) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). Specifically TAT (47-57) is located within the arginine-rich basic domain 48-60 of the TAT peptide which as a whole has three domains which function to aid HIV through transactivation, DNA binding and nuclear transport. As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. This property has been demonstrated through its ability of allowing toxins such as the neurotoxin Botulinum neurotoxin Type A, produced by the Clostridium botulinum type A bacteria to penetrate the skin barrier non-invasively. Additionally TAT (47-57) can be used to deliver proteins, fluorophores, chelators and DNA to target cells.It contains 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.

H-Thr-AMC is a small molecule that binds to the ubiquitin-proteasome system and inhibits the degradation of proteins. It has been shown to inhibit methionine aminopeptidase, which is an enzyme that degrades amino acids in the intestine. H-Thr-AMC also has a metal chelator effect, which prevents it from being degraded by proteases. The sequence of H-Thr-AMC was derived by sequencing cDNA from eukaryotes. H-Thr-AMC is not active against aminopeptidase A, but can inhibit aminopeptidase B and C. H-Thr-AMC has been shown to have inhibitory effects on both intestinal and physiological properties.br>br>
H-Thr-AMC is a substrate for the peptide:hydrolase (peptidase) family of enzymes known as aminopeptid

Z-Gly-Pro-AMC is a substrate molecule that mimics the natural substrate of dipeptidyl peptidase IV (DPP-IV) and is used in the study of plant physiology. It has been shown to inhibit DPP-IV activity by binding to the enzyme’s active site, preventing it from cleaving biologically active peptides. This drug also has an antidiabetic effect, which may be due to its ability to inhibit α-amylase activity. Z-Gly-Pro-AMC also has been shown to increase locomotor activity and reduce body weight in rats with metabolic disorders. Z-Gly-Pro-AMC inhibits serine proteases, such as trypsin, chymotrypsin, elastase, and cathepsin G, which are involved in tumor progression.
