Predicted to enable integrin binding activity; phosphatidylethanolamine binding activity; and phosphatidylserine binding activity. Involved in positive regulation of cell population proliferation and response to estrogen. Predicted to be located in external side of plasma membrane and extracellular space. Predicted to be extrinsic component of plasma membrane. Human ortholog(s) of this gene implicated in temporal arteritis. Orthologous to human MFGE8 (milk fat globule EGF and factor V/VIII domain containing). [provided by Alliance of Genome Resources, Apr 2022]
