    basic FUNCTION
  • antigen-presenting protein, that binds self and non-self lipid and glycolipid Ags and presents them to T-cell receptors on natural killer cells
  • presenting lipid A on dendritic cells (Cui 2009)
  • related to the peptide-presenting MHC class I family
  • CD1A, CD1B, CD1C, CD1D bind and present lipid-based antigens to T cells
