Predicted to enable several functions, including GTP-dependent protein binding activity; clathrin adaptor activity; and kinesin binding activity. Predicted to be involved in several processes, including Golgi to lysosome transport; endosome to melanosome transport; and positive regulation of natural killer cell degranulation. Predicted to act upstream of or within intracellular protein transport and vesicle-mediated transport. Located in perinuclear region of cytoplasm and trans-Golgi network. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and hemolymphoid system gland. Orthologous to human AP1G1 (adaptor related protein complex 1 subunit gamma 1). [provided by Alliance of Genome Resources, Apr 2022]
