ADP-ribosylation factor-like protein 4C (ARL4C)

Small GTP-binding protein that cycles between an inactive GDP-bound and an active GTP-bound form, and the speed of cycling is regulated by guanine nucleotide exchange factors (GEF) and GTPase-activating proteins (GAP). GTP-binding protein that does not act as an allosteric activator of the cholera toxin catalytic subunit.

May be involved in transportation between a perinuclear compartment and the plasma membrane, apparently linked to the ABCA1-mediated cholesterol secretion pathway. Recruits CYTH1, CYTH2, CYTH3 and CYTH4 into the plasma membrane in the GDP- bound form.
