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.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human Angiopoietin-like Protein 5/ANGPTL5 is coated at 4 μg/mL, Recombinant Human LILRB2/CD85d/ILT4 Fc Chimera binds with a typical ED50 of 0.15-0.9 μg/mL. Measured by its ability to support the adhesion of HSB2 human peripheral blood acute lymphoblastic leukemia cells. Recombinant Human LILRB2/CD85d/ILT4 Fc Chimera immobilized at 35 μg/mL, 100 μL/well, will mediate >40% HSB-2 cell adhesion (105 cells/well).
