ARL4A encodes the human gene, ADP ribosylation factor like GTPase 4A. It may also be known as: ADP-ribosylation factor-like protein 4A; ADP-ribosylation factor-like 4A; ARL4. The encoded protein has an amino acid length of 200 and a mass of 22.6 kDa. Other isoforms may exist. ARL4A is a member of the Small GTPase superfamily, Arf family. Homologs of this gene exist in other organisms, including: Fly, Rat, Zebrafish, Frog.
