ADP-ribosylation factor 1 (ARF1)

GTP-binding protein involved in protein trafficking among different compartments. Modulates vesicle budding and uncoating within the Golgi complex.

Deactivation induces the redistribution of the whole Golgi complex to the endoplasmic reticulum, suggesting a vital role in protein trafficking. In its GTP-bound form, its triggers the institution with coat proteins with the Golgi membrane.
