UniProt Comments for Cd8a
CD8A: Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains. In general heterodimer of an alpha and a beta chain linked by two disulfide bonds. Can also form homodimers. Shown to be expressed as heterodimer on thymocytes and as homodimer on peripheral blood T-lymphocytes. Interacts with the MHC class I HLA-A/B2M dimer. Interacts with LCK in a zinc-dependent manner. 2 isoforms of the human protein are produced by alternative splicing.
Protein type: Membrane protein, integral
Cellular Component: cell surface; membrane; integral to membrane; external side of plasma membrane
Molecular Function: protein binding; protein homodimerization activity; protein kinase binding
Biological Process: cell surface receptor linked signal transduction; T cell activation; immune system process; T cell mediated immunity; positive regulation of calcium-mediated signaling; cytotoxic T cell differentiation; defense response to virus
