Predicted to enable GTP binding activity and protein kinase A catalytic subunit binding activity. Involved in endocytic recycling; endothelial cell chemotaxis; and protein localization to cell leading edge. Located in several cellular components, including bicellular tight junction; endocytic vesicle; and lamellipodium. Is expressed in brain; early conceptus; lung; meninges; and secondary oocyte. Orthologous to human RAB13 (RAB13, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
