Phosphorylation Bioinformatics

Phosphorylation is one of the most prevalent and frequently studied post-translational modification (PTM). Protein phosphorylation is a PTM that plays a key role in regulating signal transduction, apoptosis, and cell cycle and replication. Despite its prevalence, phosphorylation occurs only on three amino acids: Serine (Ser; S), Threonine (Thr; T) and Tyrosine (Tyr; Y). The mechanism of phosphorylation revolves around the side chains of these amino acids. Serine, Threonine and Tyrosine have an -OH group that attacks the terminal phosphate group on ATP, thus transferring a phosphate group to the amino acid side chain. Although this reaction is unidirectional (due to the vast quantity energy released from the conversion of ATP to ADP), phosphorylation of proteins is reversible. Kinases and Phosphatases mediate the reverse reaction via the phosphorylation and dephosphorylation of substrates, respectively. Kinases mediate phosphorylation at Serine, threonine and tyrosine side chains, and phosphatases reverse protein phosphorylation by hydrolyzing the phosphate group.

NB100-56749
Western Blot: AKT1 [p Ser473] Antibody (104A282) [NB100-56749] - 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.Immunohistochemistry-Paraffin: AKT1 [p Ser473] Antibody (104A282) [NB100-56749] - IHC analysis of a formalin-fixed paraffin-embedded (FFPE) human breast carcinoma tissue section using 1:250 dilution of pSer473 AKT1 antibody (clone 104A282) on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) with 10mM 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. Some cancer cells depicted nuclear stianing also.
