ADP ribosylation factor like 4A, ADP-ribosylation factor-like protein 4A, ARL 4, ARL4A, ARL4A_HUMAN.
ADP-ribosylation factors (ARFs) are highly conserved guanine nucleotide-binding proteins that enhance the ADP-ribosyltransferase activity of cholera toxin. ARF_ are important in eukaryotic vesicular trafficking pathways and activating phospholipase D. AR
