Protein Structure
UniProt Annotation
Function Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. Involved in the down-regulation of the immune response and the development of tolerance, e.g. towards transplants. Interferes with TNFRSF5- signaling and NF-kappa-B up-regulation. Inhibits receptor-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions. {ECO:0000269PubMed:11875462, ECO:0000269PubMed:9151699}.
Subcellular Localization Cell membrane {ECO:0000269PubMed:9151699}; Single-pass type I membrane protein {ECO:0000269PubMed:9151699}. Note=Ligand binding leads to internalization and translocation to an antigen-processing compartment.
Disease Associations
Tissue Specificity Detected in monocytes, macrophages, dendritic cells, lung, natural killer cells and B-cells. {ECO:0000269PubMed:9151699, ECO:0000269PubMed:9278324, ECO:0000269PubMed:9548455}.
