Product Details

Target: LILRB4 (Leukocyte Immunoglobulin-Like Receptor, Subfamily B (With TM and ITIM Domains), Member 4 (LILRB4))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 24-238

Origin: Mouse

Source: HEK-293 Cells

Purification tag / Conjugate: This LILRB4 protein is labelled with Fc Tag.

Sequence: AA 24-238

Characteristics: This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 50.7 kDa. As a result of glycosylation, the protein migrates as 60-66 kDa under reducing (R) condition, and 120-140 kDa under non-reducing (NR) condition (SDS-PAGE).

Purity: >95 % as determined by SDS-PAGE.

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Background: Leukocyte immunoglobulin-like receptor subfamily B member 4 (LILRB4) is also known as CD85 antigen-like family member K (CD85K), Immunoglobulin-like transcript 3 (ILT-3), Leukocyte immunoglobulin-like receptor 5 (LIR-5), Monocyte inhibitory receptor HM18, which belongs to the leukocyte immunoglobulin-like receptor (LIR) family. LILRB4 / CD85K contains 2 Ig-like C2-type (immunoglobulin-like) domains. CD85K is detected in monocytes, macrophages, dendritic cells, lung, natural killer cells and B-cells. LILRB4 / CD85K is receptor for class I MHC antigens. CD85K 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. LILRB4 interferes with TNFRSF5-signaling and NF-kappa-B up-regulation and inhibits receptor-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
