CD8B encodes the CD8 beta chain isoforms of the CD8 antigen. CD8 is a cell surface glycoprotein which facilitates efficient cell-cell interactions within the immune system and is located on most cytotoxic T lymphocytes. The T-cell receptor on the T lymphocyte and the co-receptor CD8 antigen identify antigens exposed by an antigen presenting cell in the context of class I MHC molecules. The functional co-receptor is either a heterodimer composed of one alpha and one beta chain or a homodimer composed of two alpha chains. Both alpha and beta chains share substantial homology to immunoglobulin variable light chains.

CD8B 编码 CD8 抗原的 CD8 β 链异构体。 CD8 是一种细胞表面糖蛋白，可促进免疫系统内有效的细胞间相互作用，位于大多数细胞毒性 T 淋巴细胞上。 T 淋巴细胞上的 T 细胞受体和辅助受体 CD8 抗原识别在 I 类 MHC 分子的情况下由抗原呈递细胞暴露的抗原。 功能性共受体是由一条α链和一条β链组成的异二聚体或由两条α链组成的同源二聚体。 α 和 β 链都与免疫球蛋白可变轻链具有实质性的同源性。

CD8B Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 172 amino acids and having a molecular mass of 19.2 kDa. CD8B is fused to a 23 amino acid His-tag at N-terminus.
