Predicted to enable epidermal growth factor receptor binding activity and growth factor activity. Predicted to be involved in epidermal growth factor receptor signaling pathway; positive regulation of cell population proliferation; and positive regulation of mitotic nuclear division. Predicted to act upstream of or within positive regulation of cell division. Predicted to be located in extracellular region and membrane. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in gastroenteritis and pancreatic cancer. Orthologous to human TGFA (transforming growth factor alpha).
