Predicted to enable GTPase activity; guanyl ribonucleotide binding activity; and myosin V binding activity. Involved in apical protein localization; body fluid secretion; and regulation of protein localization. Located in several cellular components, including Golgi stack; apical plasma membrane; and cytoplasmic vesicle. Is anchored component of synaptic vesicle membrane. Orthologous to human RAB14 (RAB14, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
