Alternate Names for Recombinant Mouse MFG-E8 Protein
Background
Milk Fat Globulin Protein E8 (MFG-E8), also known as Lactadherin, MP47, breast epithelial antigen BA46, and SED1, is a 66‑75 kDa pleiotropic secreted glycoprotein that promotes mammary gland morphogenesis, angiogenesis, and tumor progression. MFG-E8 also plays an important role in tissue homeostasis and the prevention of inflammation (1). Mouse MGF-E8 contains two N-terminal EGF-like domains, a Pro/Thr-rich segment, and two C‑terminal F5/8-type discoidin-like domains (2). It MFG-E8 shares 63% and 94% aa sequence identity with comparable regions of human and rat MFG-E8, respectively. Alternative splicing of mouse MFG-E8 generates a short isoform lacking the Pro/Thr-rich region which contains sites for O-linked glycosylation and tyrosine sulfation (3). MFG-E8 is released into the milk in complex with lipid-containing milk fat globules. It is also found in multiple other cell types including endothelial cells and smooth muscle cells of the vasculature, immature dendritic cells, at the acrosomal cap of testicular and epididymal sperm, and in epithelial cells of the endometrium (1). MFG-E8 binds to the Integrins alpha V beta 3 and alpha V beta 5 and potentiates the angiogenic action of VEGF through VEGF R2 (4, 5). It reduces inflammation and tissue damage in a variety of settings. MFG-E8 functions as a bridge between phosphatidylserine on apoptotic cells and Integrin alpha V beta 3 on phagocytes, leading to the clearance of apoptotic debris (6). It mediates the engulfment of apoptotic bodies in atherosclerotic plaques and prion-infected brain (7, 8) and of apoptotic B cells during germinal center reactions (9, 10). MFG-E8 also promotes the removal of excess Collagen in fibrotic lungs and the regeneration of damaged intestinal epithelia (11, 12). Its tissue‑protective role impairs anti‑tumor immunity and chemotherapy‑induced apoptosis (13). MFG-E8 in the breastmilk blocks rotavirus infection in nursing babies (14).
