About This Section
| EntrezGene summary for CD1B: 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. [provided by RefSeq] UniProtKB/Swiss-Prot: CD1B_HUMAN, P29016Function: Antigen-presenting protein that binds self and non-self lipid and glycolipid antigens and presents them to T-cell receptors on natural killer T-cells |

About This Section
| UniProtKB/Swiss-Prot: CD1B_HUMAN, P29016 (See
protein sequence)Recommended Name: T-cell surface glycoprotein CD1b precursor Size: 333 amino acids; 36939 Da
Subunit: Heterodimer with B2M (beta-2-microglobulin). Interacts with saposin C
Subcellular location: Cell membrane; Single-pass type I membrane protein. Endosome membrane. Lysosome membrane. Note=Subject to intracellular trafficking between the cell membrane, endosomes and lysosomes. Localizes to cell surface lipid rafts
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 lysososme
Sequence caution: Sequence=CAI10852.1; Type=Erroneous gene model prediction;
