This gene encodes a member of the CD1 family of transmembrane glycoproteins, which are structurally related to the major histocompatibility complex (MHC) proteins and form heterodimers with beta-2-microglobulin. The CD1 proteins mediate the presentation of primarily lipid and glycolipid antigens of self or microbial origin to T cells. The human genome contains five CD1 family g... See more...

Summaries for CD1B Gene

Entrez Gene Summary for CD1B Gene

  • This gene encodes a member of the CD1 family of transmembrane glycoproteins, which are structurally related to the major histocompatibility complex (MHC) proteins and form heterodimers with beta-2-microglobulin. The CD1 proteins mediate the presentation of primarily lipid and glycolipid antigens of self or microbial origin to T cells. The human genome contains five CD1 family genes organized in a cluster on chromosome 1. The CD1 family members are thought to differ in their cellular localization and specificity for particular lipid ligands. The protein encoded by this gene localizes to late endosomes and lysosomes via a tyrosine-based motif in the cytoplasmic tail, and requires vesicular acidification to bind lipid antigens.

GeneCards Summary for CD1B Gene

CD1B (CD1b Molecule) is a Protein Coding gene. Diseases associated with CD1B include Mycobacterium Malmoense and Non-Langerhans-Cell Histiocytosis. Among its related pathways are Amoebiasis and Class I MHC mediated antigen processing and presentation. Gene Ontology (GO) annotations related to this gene include beta-2-microglobulin binding and endogenous lipid antigen binding. An important paralog of this gene is CD1C.

    Quaternary structure:
    • Heterodimer with B2M (beta-2-microglobulin). Interacts with saposin C.
    Miscellaneous:
    • During protein synthesis and maturation, CD1 family members bind endogenous lipids that are replaced by lipid or glycolipid antigens when the proteins are internalized and pass through endosomes or lysosomes, before trafficking back to the cell surface. Interaction with saposin C is required for the loading of bacterial lipid antigens onto CD1B in the lysosome.
