LILRB4

Gene
LILRB4
Protein
Leukocyte immunoglobulin-like receptor subfamily B member 4
Organism
Homo sapiens
Length
448 amino acids
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, e.g. towards transplants. Interferes with TNFRSF5-signaling and NF-kappa-B up-regulation. Inhibits receptor-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
