Recombinant Human CD47(His Tag)

CD47, also known as Integrin-Associated Protein (IAP) and OA3, is a 40-60 kDa variably glycosylated atypical member of the immunoglobulin superfamily . Human CD47 is an integral membrane protein that consists of a 123 amino acid (aa) extracellular domain (ECD) with a single Ig-like domain, five membrane-spanning regions with short intervening loops, and a 34 aa C-terminal cytoplasmic tail. Alternate splicing of human CD47 generates additional isoforms with deletions in the cytoplasmic tail. Within the N-terminal ECD, human CD47 shares 63% aa sequence identity with mouse and rat CD47. A portion of the Nterminal ECD can by shed from smooth muscle cells by MMP-2-mediated proteolysis. The ubiquitously expressed CD47 binds to SIRP family members on macrophages, neutrophils, and T cells. These interactions prevent macrophage-mediated clearance of healthy CD47-expressing cells and promote immune cell transmigration across the vascular endothelium. The CD47-SIRP alpha interaction is species specific, and this lack of cross-species interaction has been implicated in xenotransplantation rejection.
