    Protocol

    Product Description

    PTMScan® Technology employs a proprietary methodology from Cell Signaling Technology (CST) for peptide enrichment by immunoprecipitation using a specific bead-conjugated antibody in conjunction with liquid chromatography (LC) tandem mass spectrometry (MS/MS) for quantitative profiling of post-translational modification (PTM) sites in cellular proteins. These include phosphorylation (PhosphoScan®), ubiquitination (UbiScan®), acetylation (AcetylScan®), and methylation (MethylScan®), among others. PTMScan® Technology enables researchers to isolate, identify, and quantitate large numbers of post-translationally modified cellular peptides with a high degree of specificity and sensitivity, providing a global overview of PTMs in cell and tissue samples without preconceived biases about where these modified sites occur.

    Background

    As an integral part of the machinery of cellular function, proteins undergo regulation by a variety of post-translational modifications. One of the most prevalent and widely studied PTMs is serine/threonine phosphorylation. Prominent kinases targeting consensus substrate motifs account for tens of thousands of known and predicted sites on more than 13,000 human proteins (1-3). Cell Signaling Technology has developed phospho-Ser/Thr motif antibodies for proteomic profiling of kinase substrates. Arg-directed or AGC-family kinases including PKA, PKG, PKC, Akt, p70 S6 kinase, AMPK, and RSK and are characterized by preference for basic amino acids (Lys or Arg) especially Arg at position -3 relative to the phosphorylated Ser or Thr (1,4). Akt, p70S6 kinase and RSK additionally share specificity for Lys or Arg at position -5 (5). CST™ has developed a Basophilic PTMScan® kit comprising a pool of antibodies that recognize basophilic kinase substrate motifs as a powerful proteomics analysis tool for investigating the regulation of phosphorylation by Arg-directed kinases, as well as for high throughput kinase drug discovery.
