Description

This product was prepared from monospecific antiserum by immunoaffinity chromatography using a phospho peptide coupled to agarose beads followed by solid phase adsorption(s) against a non-phospho peptide and non-specific peptide to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Background: Akt1

AKT (also known as protein kinase B (PKB) and RAC (related to A and C kinases)) is a critical intracellular serine/threonine kinase that translates signals from extracellular stimuli including growth factors, cytokines and neurotransmitters (1). AKT signaling plays critical roles in cell growth, proliferation, survival and differentiation (1). It is also involved in organogenesis, angiogenesis and metabolism. Three mammalian AKT isoforms have been identified. The AKT pathway can be activated by any of the three members who share a high level of protein homology but are independently encoded by AKT1 (PKB alpha; 14q32.32), AKT2 (PKB beta; 19q13.2), or AKT3 (PKB gamma; 1q44) (1, 2). Each AKT family member contains an N-terminal pleckstrin homology (PH) domain, a central kinase domain, and a C-terminal regulatory domain. AKT mediates many of the downstream events of phosphatidylinositol 3-kinase (PI3-K), a lipid kinase activated by growth factors, cytokines and insulin. PI3-K recruits AKT to the membrane, where it is activated by PDK1 phosphorylation. AKT has two main phosphorylation sites (Ser473 and Thr308, predicted molecular weight 56 kDa) (3, 4). Once phosphorylated, AKT dissociates from the membrane and phosphorylates targets in the cytoplasm and the cell nucleus including mammalian target of rapamycin (mTOR).

The main function of AKT is to control inhibition of apoptosis and promote cell proliferation. Survival factors can activate AKT Ser473 and Thr308 phosphorylation sites in a transcription-independent manner, resulting in the inactivation of apoptotic signaling transduction through the tumor suppressor PTEN, an antagonist to PI3-K (5). PTEN exerts enzymatic activity as a phosphatidylinositol-3,4,5-trisphosphate (PIP3) phosphatase, opposing PI3K activity by decreasing availability of PIP3 to proliferating cells, leading to overexpression and inappropriate activation of AKT noted in many types of cancer.

AKT1 function has been linked to overall physiological growth and function (2). AKT1 has been correlated with proteus syndrome, a rare disorder characterized by overgrowth of various tissues caused by a mosaic variant in the AKT1 gene in humans.

AKT2 is strongly correlated with Type II diabetes, including phenotypes of insulin resistance, hyperglycemia and atherosclerosis (2, 6).

The function of AKT3 is specifically associated to brain development, where disruptions to AKT3 are correlated with microcephaly, hemimegalencephaly, megalencephaly and intellectual disabilities (2).
