Plekhg3 encodes the human gene, Pleckstrin homology and RhoGEF domain containing G3. It may also be known as: Pleckstrin homology domain-containing family G member 3; PH domain-containing family G member 3; ARHGEF43; KIAA0599; pleckstrin homology domain containing, family G (with RhoGef domain) member 3. The encoded protein has an amino acid length of 1219 and a mass of 134.4 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog, Chicken.
