DESCRIPTION

Also known as LIRB1_HUMAN, LILRB1, ILT2, LIR1, MIR7. Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles (PubMed:16455647, PubMed:28636952). Receptor for H301/UL18, a human cytomegalovirus class I MHC homolog. Ligand binding results in inhibitory signals and down-regulation of the immune response. Engagement of LILRB1 present on natural killer cells or T-cells by class I MHC molecules protects the target cells from lysis. Interaction with HLA-B or HLA-E leads to inhibition of FCER1A signaling and serotonin release. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions (PubMed:11907092, PubMed:9285411, PubMed:9842885). Recognizes HLA-G in complex with B2M/beta-2 microglobulin and a nonamer self-peptide (PubMed:16455647). Upon interaction with peptide-bound HLA-G-B2M complex, triggers secretion of growth-promoting factors by decidual NK cells (PubMed:29262349, PubMed:19304799). Reprograms B cells toward an immune suppressive phenotype (PubMed:24453251). Binds PTPN6 when phosphorylated (PubMed:9285411). Binds FCER1A and FCGR1A (PubMed:9842885, PubMed:11907092). Interacts with human cytomegalovirus/HHV-5 protein UL18 (PubMed:10591185). Interacts with peptide-bound HLA-G-B2M complex (PubMed:16455647). Interacts with peptide-bound HLA-F-B2M complex but not with peptide-free HLA-F open conformer. It does not probe the peptide sequence directly (PubMed:28636952).
