Protein coats deform flat lipid membranes into buds and capture membrane proteins to form transport vesicles. The assembly-disassembly cycle of the COPI coat on Golgi membranes is coupled to the GTP-GDP cycle of the small G protein ARF1. ARFGAP1 contributes to vesicle budding by increasing the GTPase activity of ARF1, because it promotes hydrolysis of the ARF1-bound GTP and thus, is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles, a prerequisite for vesicle's fusion with target compartment. for ARFGAP1 may has a role in regulating the GTPase activity and neuronal toxicity of LRRK2; reciprocally, LRRK2 phosphorylates ArfGAP1 and is required for ArfGAP1 neuronal toxicity.
