  • CD1,
  • CD1A,
  • cortical thymocyte antigen CD1A,
  • HTA1,
  • FCB6,
  • cluster of differentiation 1 A,
  • hTa1 thymocyte antigen,
  • T-cell surface glycoprotein CD1a,
  • T6,

  • CD1A antigen, a polypeptide,
  • differentiation antigen CD1-alpha-3,


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.
