Predicted to enable small GTPase binding activity. Predicted to be involved in Golgi to plasma membrane protein transport and protein localization to cell surface. Predicted to act upstream of or within protein transport. Predicted to be located in clathrin-coated vesicle and trans-Golgi network. Is expressed in several structures, including branchial arch; heart; liver; lung; and white fat. Orthologous to human GGA2 (golgi associated, gamma adaptin ear containing, ARF binding protein 2).
