Summary: Enables GTPase activity and Golgi transport complex binding activity. Involved in several processes, including cytoskeleton-dependent cytokinesis; positive regulation of cellular component organization; and positive regulation of insulin secretion. Located in Golgi apparatus; cleavage furrow; and endoplasmic reticulum exit site. Is expressed in several structures, including adult ensheathing glial cell; brain; imaginal disc; mushroom body; and synaptic neuropil domain. Orthologous to several human genes including RAB1A (RAB1A, member RAS oncogene family) and RAB1B (RAB1B, member RAS oncogene family). [provided by Alliance of Genome Resources, Dec 2024]

Title: A novel function for Rab1 and Rab11 during secretory granule maturation.
It has been demonstrated that the COG complex cooperates with Rab1 and GOLPH3 to regulate Golgi trafficking, and that overexpression of Rab1 can rescue the cytokinesis and locomotor defects associated with loss of Cog7.
