Predicted to enable mRNA binding activity. Predicted to be involved in Golgi vesicle transport and intracellular protein transport. Predicted to act upstream of or within pancreatic juice secretion; protein localization to axon; and protein localization to cell leading edge. Predicted to be located in several cellular components, including COPI-coated vesicle; Golgi apparatus; and growth cone. Predicted to be part of COPI vesicle coat. Orthologous to human COPA (COPI coat complex subunit alpha). [provided by Alliance of Genome Resources, Apr 2022]
