Enables epidermal growth factor receptor binding activity and growth factor activity. Involved in epidermal growth factor receptor signaling pathway; negative regulation of elastin biosynthetic process; and positive regulation of cell growth. Predicted to be located in cell surface. Predicted to be active in extracellular space. Predicted to be integral component of plasma membrane. Biomarker of acute kidney failure. Human ortholog(s) of this gene implicated in glomerulosclerosis and perinatal necrotizing enterocolitis. Orthologous to human HBEGF (heparin binding EGF like growth factor).
