Alternative:
Immunoglobulin-like transcript 2(ILT-2);CD85 antigen-like family member J;Monocyte/macrophage immunoglobulin-like receptor 7(MIR-7);
CD:

Organism:

General Annotation
Sub Unit:
Binds PTPN6 when phosphorylated. Binds FCER1A and FCGR1A.
Function:
Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. 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 the signal triggered by FCER1A and inhibits serotonin release. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
