CD1A (Thymocyte antigen CD1A) also known as CD1, is a human  protein  encoded by the  CD1A gene. CD1A  is 1 of 5 distinct CD1 genes that are variably conserved in different mammalian species.  This gene encodes a member of the CD1 family of transmembrane glycoproteins, which are structurally related to the major histocompatibility complex (MHC) proteins and form heterodimers with beta-2-microglobulin.The CD1A gene is mapped on 1q23.1. The CD1 proteins mediate the presentation of primarily lipid and glycolipid antigens of self or microbial origin to T cells.  CD1A  is concentrated in the early or recycling endosome. Moody et al. (2004)   reported that  CD1A  presents to T cells a family of previously unknown lipopeptides from Mycobacterium tuberculosis, named didehydroxymycobactins because of their structural relation to mycobactin siderophores.  The protein encoded by this gene localizes to the plasma membrane and to recycling vesicles of the early endocytic system. Apolipoprotein E (107741) binds lipid antigens and delivers them by receptor-mediated uptake into endosomal compartments containing CD1 in antigen-presenting cells.
