Recombinant Human LILRB2 Protein (Gln22-His458), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10067
Official Symbol
LILRB2
Product Overview
Recombinant human LILRB2/CD85d/ILT4 protein (Gln22-His458) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
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.
