AKT3 encodes the human gene, V-akt murine thymoma viral oncogene homolog 3. It may also be known as: RAC-gamma serine/threonine-protein kinase; Protein kinase Akt-3; Protein kinase B gamma; PKB gamma; RAC-PK-gamma; STK-2; RAC-gamma serine/threonine-protein kinase ; protein kinase B, gamma; MPPH2; PKB-GAMMA; PKBG; PRKBG; RAC-gamma. The encoded protein is an enzyme with an amino acid length of 479 and a mass of 55.8 kDa. Other isoforms may exist. AKT3 is a member of the Protein kinase superfamily, AGC Ser/Thr protein kinase family, RAC subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Arabidopsis, Zebrafish, Chicken.
