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

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

immunity/defense

PATHWAY

metabolism

signaling

signal transduction

a component	constituent of membrane glycoprotein
	forming heterodimer with beta-2-microglobulin

INTERACTION

DNA

RNA

small molecule

protein	B2M associated
	interacting with saposin C

cell & other

REGULATION

Other

Ag capture is regulated by pH, requiring vesicular acidification to bind lipid antigens (Relloso 2008)
