CD1D, also known as antigen-presenting glycoprotein CD1d isoform 1, is a transmembrane glycoprotein in the CD1 family of glycolipid antigen-presenting MHC-like molecules. CD1d-presented lipid antigens activate a special class of T cells, known as natural killer T (NKT) cells, through the interaction with the T-cell receptor present on NKT membranes. When activated, NKT cells rapidly produce Th1 and Th2 cytokines, typically represented by interferon-gamma and interleukin 4 production. Recombinant human CD1D protein, fused to His-Tag at C-terminal, expressed in insect cell and purified by using conventional chromatography techniques.
