Target description

Antigen-presenting glycoprotein CD1d (UniProt: P15813; also known as R3G1, CD1d) is encoded by the CD1D gene (Gene ID: 912) in human. Cd1d is a single-pass type 1 membrane glycoprotein, which is synthesized with a signal peptide (aa 1-19) that is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 20-301), a transmembrane domain (aa 302-322), and a short cytoplasmic domain (aa 323-335). It is expressed at high levels by human cortical thymocytes, and its expression is also observed on certain T cell leukemias. It serves as a key antigen-presenting molecule involved in the selection and activation of NK cells. It is a major-histocompatibility-complex (MHC) class-I-like molecule that presents self-lipid and non-self-lipid antigens to invariant natural killer T (iNKT) cells. Following engagement of the invariant T cell receptor (iTCR) by CD1d lipid complexes, iNKT cells proliferate, produce cytokines, and become cytotoxic, regulating innate and adaptive immune responses.
