[Expressed in mammary epithelia and activated macrophages by human MFGE8 Gene, 387-aa 43-kDa (precursor) Milk Fat Globule-EGF Factor 8 Protein is a multidomain cell surface (and secreted) protein that contains an EGF-like domain, C-terminal F5/8 type C domains, and the cell adhesion tripeptide RGD. MFGE8 recognizes aminophospholipids (phosphatidylserine) and binds to cells via its RGD motif; MFGE8 binds strongly to cells expressing alpha-V-beta-3 integrin. Expressed by activated macrophages, MFGE8 specifically binds to apoptotic cells and appears to promote macrophage phagocytosis of apoptotic cells. MFGE8 is overexpressed in several carcinomas.
