Predicted to enable GTP binding activity; GTPase activity; and cytoskeletal protein binding activity. Involved in melanosome transport. Acts upstream of or within positive regulation of axon extension and protein localization to cell surface. Located in several cellular components, including axon; perinuclear region of cytoplasm; and recycling endosome. Is expressed in several structures, including adrenal gland; early conceptus; esophagus; eye; and genitourinary system. Orthologous to human RAB11A (RAB11A, member RAS oncogene family).
