Enables cytoskeletal protein binding activity; protein kinase A binding activity; and small GTPase binding activity. Predicted to be involved in positive regulation of insulin secretion. Predicted to act upstream of or within vesicle transport along actin filament. Located in several cellular components, including actin cytoskeleton; melanosome; and photoreceptor outer segment. Part of exocyst. Is expressed in several structures, including gut; heart; lung; male reproductive gland or organ; and nervous system. Orthologous to human MYRIP (myosin VIIA and Rab interacting protein).
