Previous GeneCards Identifiers for LILRB2 Gene
This gene is a member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The receptor is expressed on immune cells where it binds to MHC class I molecules on antigen-presenting cells and transduces a negative signal that inhibits stimulation of an immune response. It is thought to control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
GeneCards Summary for LILRB2 Gene
LILRB2 (Leukocyte Immunoglobulin-Like Receptor, Subfamily B (With TM And ITIM Domains), Member 2) is a Protein Coding gene. Among its related pathways are Immune System and Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell. GO annotations related to this gene include receptor activity and protein phosphatase 1 binding. An important paralog of this gene is KIR2DL4.
UniProtKB/Swiss-Prot for LILRB2 Gene
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.
