Peptides & Amino Acids

NY-ESO-1 (157-165) peptide – SLLMWITQC HLA-A*02 Major Histocompatibility Complex (MHC) allele HLA-A*02 allele is expressed in class I Human MHC Leukocyte Antigens (HLA), that are cell surface receptors, presenting peptides to the immune system. If a non-self-peptide is recognized by cytotoxic T-cells in the blood, cell death will be initiated via apoptosis. NY-ESO-1 protein Peptides presented by MHC class I molecule, are usually between 7 and 11 amino acids, originating from proteins expressed by the cell. SLLMWITQC peptide derives from New York esophageal squamous cell carcinoma 1 (NY-ESO-1 : UniProt – P78358) protein, which 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 it is also expressed in 82% of neuroblastomas and 46% of melanomas, as well as in many other solid tumors and hematological malignancies. NY-ESO-1 (157-165) peptide application Class I

[Glu2]-TRH tripeptide – pGlu-Glu-Pro-NH2 (CAS: 85541-78-2) Thyrotropin-releasing hormone (TRH) Thyrotropin-releasing hormone (TRH) is a tripeptide hypothalamic regulatory hormone that regulates the release of thyroid-stimulating hormone (TSH), as well as prolactin (for breasts growth and milk production during and after pregnancy). To obtain thyrotropin-releasing hormones, 6 pro-TRH peptides have first to be obtained from the larger preproTRH precursor (UniProt: P20396). These octapeptides are then cleaved between Arginine/Glutamine and Glutamine/Lysine residues to release 6 Gln-His-Pro-Gly peptides that will be enzymatically converted in pGln-His-Pro-NH2 peptides (pGln representing pyroglutamine). After TRH maturation (1) in neurons located in the pituitary gland, the hormone will be transported along axons (2) to reach the hypophyseal portal system via exocytosis (3). Once the thyrotrophs reached, thyrotropin-releasing hormone binds TRH-receptor (4) to enable TSH synthesis a

ALPHA FACTOR SIGNALING PEPTIDE Yeast mating signaling pathway The life cycle of Saccharomyces cerevisiae, also known as the brewer’s and the baker’s yeast, is characterized by both haploid and diploid phases. Indeed, yeasts are organized in two haploid types, known as a and α cells (MATa and MATα), that can either proliferate individually, using mitosis, or fuse together to form MATa/MATα diploids. α factor - WHWLQLKPGQPMY peptide - CAS: 59401-28-4. Haploid, diploid cells For two haploid cells to mate, mating factors are needed. These pheromones induce G-Protein Coupled Receptor‘s (GPCR) conformational changes, which allow G-protein migration in the plasma membrane. GPCRs are present on both a and α yeast cells and turn into Guanine nucleotide Exchange Factors (GEF) upon G-protein release. The receptor’s « new activity » leads to guanosine diphosphate (GDP) exchange by guanosine triphosphate (GTP) on the G-protein, which will recruit STE 5 to allow Fus3 protein phosphorylation
