Predicted to enable several functions, including GTP binding activity; GTPase activity; and enzyme activator activity. Predicted to be involved in several processes, including activation of phospholipase D activity; protein localization to Golgi apparatus; and retrograde transport, endosome to Golgi. Located in cytoplasm. Is expressed in genitourinary system and inner ear. Orthologous to human ARL1 (ADP ribosylation factor like GTPase 1). [provided by Alliance of Genome Resources, Apr 2022]
