View in BioMuta


CD1A is a transmembrane glycoprotein that is structurally related to the major histocompatibility complex (MHC) proteins and forms heterodimers with beta-2-microglobulin. CD1A functions as an antigen-presenting protein that binds self and non-self lipid and glycolipid antigens and presents them to T-cell receptors on natural killer T-cells.
