Description de la cible

H-2 class I histocompatibility antigen, K-B alpha chain (UniProt: P01901; also known as H-2K(B)) is encoded by the H2-K1 (also known as H2-K) gene (Gene ID: 14972) in murine species. Major histocompatibility complexes (MHCs) are cell surface molecules that play a major part of the immune system in all vertebrates by determining histocompatibility. The main function of MHCs is to bind and present peptide fragments derived from pathogens on the surface of antigen presenting cells. MHCs are divided into two major classes, class I MHCs are heterodimers composed of a transmembrane -chain and a common extracellular β-chain. The -chain contains three domains ( 1, 2, and 3), with the 1 domain mediating interaction with the β2 subunit. The 1 and 2 domains form the antigen-binding groove. H2-Kb, a member of the MHV class I family, is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 22-305), a transmembrane domain (aa 306-328), and a cytoplasmic domain (aa 329-369). It is involved in the presentation of foreign antigens to the immune system, particularly to T cells expressing CD3/TCR and CD8. The peptide-binding site of H2-Kb contains a deep C pocket, which is critical for peptide binding, as it accepts the anchor phenylalanine or tyrosine residue located in the middle of H2-Kb binding peptides. It predominantly binds octameric peptides. Clone 25D1.16 is shown to be specific for the ovalbumin-derived peptide SIINFEKL (OVA257-264) bound to the MHC class I molecule H-2Kb. This clone reacts with cells pulsed with SIINFEKL and with cells pulsed with V-OVA. (Ref.: Ferez, M., et al. (2014). J. Immunol. 192; 52-58; Porgador, A., et al. (1997). Immunity. 6; 715-726).
