Active Recombinant Human LILRA1 protein, His-tagged

• Cat.No.: LILRA1-267H
• Product Overview: Recombinant Human LILRA1(Pro17-Asn461) fused with His tag at C-terminal was expressed in NS0.

Specification

• Description: LILRA1, also known as CD85i and LIR-6, is an approximately 70 kDa variably glycosylated transmembrane protein that regulates immune cell activation. Mature human LILRA1 consists of a 445 amino acid (aa) extracellular domain (ECD) with 4 Ig-like domains, a 21 aa transmembrane segment, and a 7 aa cytoplasmic tail. The transmembrane segment contains a positively charged arginine which may mediate association with signaling molecules. Alternative splicing generates an isoform that lacks the third and fourth Ig-like domains. LILRA1 is expressed on monocytes and binds to the free heavy chain of the MHC class I molecule HLA-B27. It is activated in response to the BCG mycobacterial strain. R&D Systems in-house testing indicates that LILRA1 binds to Angiopoietin-like 7, consistent with the demonstrated functional interactions between other members of these protein families.
