AP1G1, a protein that in humans is encoded by the AP1G1 gene, together with medium and small subunits, form a heterotetrameric complex called an adaptor and the protein encoded by this gene is a gamma-adaptin protein.
AP-1 complex subunit gamma-1 is a protein that in humans is encoded by the AP1G1 gene. Adaptins, together with medium and small subunits, form a heterotetrameric complex called an adaptor, whose role is to promote the formation of clathrin-coated pits and vesicles. The protein encoded by this gene is a gamma-adaptin protein and it belongs to the adaptor complexes large subunits family.
