Predicted to enable structural molecule activity. Predicted to be involved in several processes, including Golgi vesicle transport; establishment of Golgi localization; and organelle transport along microtubule. Predicted to act upstream of or within protein transport. Located in Golgi membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and skeleton. Orthologous to human COPG1 (COPI coat complex subunit gamma 1).
