Predicted to enable structural molecule activity. Predicted to be involved in Golgi vesicle transport; organelle transport along microtubule; and protein secretion. Predicted to act upstream of or within protein transport. Located in COPI-coated vesicle; Golgi membrane; and growth cone. Is expressed in brain and early conceptus. Orthologous to human COPG2 (COPI coat complex subunit gamma 2). [provided by Alliance of Genome Resources, Apr 2022]
