Predicted to enable GDP binding activity and GTPase activity. Predicted to be involved in several processes, including immunoglobulin transcytosis in epithelial cells mediated by polymeric immunoglobulin receptor; plasma membrane bounded cell projection assembly; and regulation of plasma membrane bounded cell projection organization. Predicted to be located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and cytoplasmic vesicle. Predicted to be active in early endosome; plasma membrane; and recycling endosome membrane. Orthologous to human RAB17 (RAB17, member RAS oncogene family).
