Term Name: T-cell surface glycoprotein CD8 alpha chain
Synonyms: CD8a, Lyt-2, Lyt2, MAL, T-cell surface glycoprotein Lyt-2, T-lymphocyte differentiation antigen T8/Leu-2
Definition: A protein that is a translation product of the human CD8A gene or a 1:1 ortholog thereof. CD8 is a transmembrane that is a co-receptor for MHC class-I antigen/T-cell receptor interaction. The most common form of CD8 is composed of a CD8 alpha and a CD8 beta chain.
