Predicted to enable several functions, including T cell receptor binding activity; lipid antigen binding activity; and lipopeptide binding activity. Predicted to be involved in several processes, including antigen processing and presentation, endogenous lipid antigen via MHC class Ib; antigen processing and presentation, exogenous lipid antigen via MHC class Ib; and regulation of T cell proliferation. Predicted to act upstream of or within several processes, including positive regulation of cytokine production; positive regulation of leukocyte activation; and positive thymic T cell selection. Predicted to be located in several cellular components, including cell surface; endosome; and lysosome. Predicted to be active in external side of plasma membrane and extracellular space. Human ortholog(s) of this gene implicated in pulmonary tuberculosis. Orthologous to human CD1D (CD1d molecule). [provided by Alliance of Genome Resources, Apr 2022]
