Rabbit anti-Human LILRB3 Polyclonal Antibody

Uniprot Id

O75022

Target Species

Human

Target Name

LILRB3

Target Full Name

Leukocyte immunoglobulin-like receptor subfamily B member 3

Target Function

May act as receptor for class I MHC antigens. Becomes activated upon coligation of LILRB3 and immune receptors, such as FCGR2B and the B-cell receptor. Down-regulates antigen-induced B-cell activation by recruiting phosphatases to its immunoreceptor tyrosine-based inhibitor motifs (ITIM).

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein.

Target Tissue Specificity

Detected in monocytes and B-cells.

Target Synonyms

LILRB3; ILT5; LIR3; Leukocyte immunoglobulin-like receptor subfamily B member 3; LIR-3; Leukocyte immunoglobulin-like receptor 3; CD85 antigen-like family member A; Immunoglobulin-like transcript 5; ILT-5; Monocyte inhibitory receptor HL9; CD antigen CD85a

Target Background

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.
