== Function ==
[https://www.uniprot.org/uniprot/LIRB2_HUMAN LIRB2_HUMAN] 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.<ref>PMID:9548455</ref> <ref>PMID:9842885</ref> <ref>PMID:11875462</ref> <ref>PMID:12853576</ref>
