Predicted to enable GTPase activity; guanyl ribonucleotide binding activity; and identical protein binding activity. Predicted to be involved in several processes, including negative regulation by host of symbiont catalytic activity; positive regulation of exocytosis; and retrograde transport, endosome to Golgi. Predicted to be located in cytoplasmic vesicle membrane and melanosome. Predicted to be active in late endosome; lysosome; and phagocytic vesicle. Orthologous to human RAB9A (RAB9A, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
