CD8A / CD8 Alpha

CD8a molecule

The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class I MHC molecules. The coreceptor functions as either a homodimer composed of two alpha chains or as a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 alpha chain. Multiple transcript variants encoding different isoforms have been found for this gene.

Gene Name:	CD8a molecule
Synonyms:	CD8A, CD8a molecule, CD8a antigen, OKT8 T-cell antigen, Leu2 T-lymphocyte antigen, T8 T-cell antigen, T cell co-receptor, p32, CD8, Leu2, T-cell antigen Leu2
Target Sequences:	NM_001768 NP_001759.3 P01732
