Predicted to enable small GTPase binding activity. Involved in Golgi to plasma membrane transport and protein localization to ciliary membrane. Acts upstream of or within positive regulation of protein catabolic process and toxin transport. Predicted to be located in Golgi apparatus; early endosome; and nucleoplasm. Predicted to be part of protein-containing complex. Is expressed in several structures, including genitourinary system; gut; nervous system; respiratory system; and white fat. Orthologous to human GGA1 (golgi associated, gamma adaptin ear containing, ARF binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
