CD1d is a lipid antigen-presenting molecule and a member of the group II CD1 family expressed by humans and mice.{60764} It is composed of a heavy chain, a transmembrane region, and a short intracellular C-terminal tail.{60764} The heavy chain contains three extracellular domains that associate with the light-chain β2-microglobulin. It is expressed primarily by antigen-presenting cells.{60764,60765} CD1d is directly involved in the process of presenting lipid antigens to T cells and invariant natural killer T (iNKT) cells to induce an immune response, including the secretion of specific cytokines depending on the antigen presented. Activation of iNKT cells by CD1d presentation of α-galactosylceramide (α-GalCer) in a murine model of melanoma reduces the number of metastases, but only when bone marrow-derived dendritic cells (BMDCs) were used to prolong iNKT cell responses.{60766} Cayman’s CD1d Extracellular Domain/B2M Heterodimer (human, recombinant) protein consists of 393 amino acids and has a calculated molecular weight of 45 kDa (33.3 (CD1d) + 11.7 (B2M) kDa). By SDS-PAGE, under reducing conditions, the apparent molecular mass of the protein is 55.7 kDa (43.2 (CD1d) + 12.5 (B2M) kDa) due to glycosylation.
