Arf function on vesicles is regulated by
A) phosphorylation of serine residues.
B) phosphorylation of mannose residues.
C) binding of GTP.
D) binding of ATP.

Question

Quizplus · Accepted Answer

Arf (ADP-ribosylation factor) function on vesicles is regulated by the binding of GTP. Arf proteins are small GTPases that play a crucial role in vesicle formation and trafficking by cycling between an active GTP-bound state and an inactive GDP-bound state.
