Scientific Data Images for AKT1 [p Ser473] Antibody (104A282) - BSA Free

Western Blot: AKT1 [p Ser473] Antibody (104A282) [NB100-56749] - Total protein from mouse 3T3 cells treated with and without PDGF (50 ng/mL) for the indicated times was separated on a 7.5% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2.0 ug/mL anti-AKT1 (NBP2-01725) and 2 ug/mL pS473 AKT1 in 1% BSA in TBST and detected with an anti-mouse HRP secondary antibody using chemiluminescence. Note the detection of phosphorylated AKT1 in response to PDGF treatment compared to total AKT1 protein.
Western Blot: AKT1 [p Ser473] Antibody (104A282) [NB100-56749] - WB of phospho AKT using phospho AKT antibody at 2 ug/mL against untreated (lane 1) and PDGF treated (lane 2) NIH-3T3 lysate. HRP conjugated secondary antibody and ECL substrate solution were used for this test. Image using the Azide and BSA Free form of this antibody.
Immunohistochemistry-Paraffin: AKT1 [p Ser473] Antibody (104A282) [NB100-56749] - IHC analysis of an FFPE human breast carcinoma tissue section using 1:250 dilution of phospho Ser473 AKT1 antibody (clone 104A282) on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) with 10 mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching using peroxide block. The sections were incubated with primary antibody for 30 minutes. Bond Polymer Refine Detection (Leica Biosystems) and DAB were used for signal detection which followed counterstaining with hematoxylin. Whole slide scanning and capturing of representative images (20X) were performed using Aperio AT2 (Leica Biosystems). This antibody generated a diffused cytoplasmic staining of phosphor-AKT (Ser-473) in the cancer cells as well as the stromal cells. Staining was performed by Histowiz.

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).
