ADP-ribosylation factor-like protein 4D (ARL4D)

Small GTP-binding protein that cycles between an inactive GDP-bound and an energetic GTP-bound form, and the rate 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.

Recruits CYTH1, CYTH2, CYTH3 and CYTH4 into the plasma membrane in GDP-bound form. .
