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. Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions. {ECO:0000269PubMed:11875462, ECO:0000269PubMed:12853576, ECO:0000269PubMed:9548455, ECO:0000269PubMed:9842885}.

Subcellular Localization

Membrane; Single-pass type I membrane protein.

Disease Associations

Tissue Specificity

Expressed on monocytes and B-cells, and at lower levels on dendritic cells. Detected at low levels in natural killer (NK) cells. {ECO:0000269PubMed:9548455, ECO:0000269PubMed:9842885}.
