Anti-AKT antibodies are protein reagents that detect specific antigens. The AKT antigen is another term for the human protein AKT serine/threonine kinase 1, encoded by the AKT1 gene. The protein is known to function in the apoptotic pathway and cell differentiation, among other biological roles. Canonically, it has an amino acid length of 480 residues and a mass of 55.7 kilodaltons. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm and it is reported to be expressed in prostate cancer and levels increase from the normal to the malignant state. The AKT protein is a member of the AGC Ser/Thr protein kinase protein family. Other alias names for AKT include PKB.
