Predicted to enable GTP binding activity and GTPase activity. Predicted to be involved in several processes, including anterograde axonal transport; autophagosome-lysosome fusion; and late endosome to lysosome transport. Predicted to act upstream of or within cell division; chromosome segregation; and protein transport. Predicted to be located in lysosome. Predicted to be active in lysosomal membrane. Orthologous to human ARL8B (ARF like GTPase 8B).
