The CD1D2 protein plays a crucial role as an antigen-presenting molecule, binding self and non-self glycolipids and presenting them to T-cell receptors on natural killer T-cells. In partnership with B2M, it mediates immune responses, and its interactions with MHC II and CD74 highlight its significance in the complex network of immune system regulation. CD1D2-B2M Heterodimer Protein, Mouse (HEK293, His) is a recombinant protein dimer complex containing mouse-derived CD1D2-B2M Heterodimer protein, expressed by HEK293 , with C-His labeled tag.
