PTMScan® HS Pilot Acetyl-Lysine Motif (Ac-K) Kit #50071
Motif analysis using all acetyl-lysine peptides enriched and identified by PTMScan® HS Pilot Acetyl-Lysine Motif (Ac-K) Kit from two different samples. One milligram each of mouse embryo and HCT 116 human colon cancer cells were independently digested with trypsin and immunoprecipitated with PTMScan® HS Acetyl-Lysine (Ac-K) Magnetic Immunoaffinity Beads. Orbitrap Fusion™ Lumos™ mass spectrometer analysis identified a total of 5,229 non-redundant sites. The motif logo shows that the Ac-K antibody is a general motif antibody that recognizes the Ac-K motif independent of protein context, without other amino acid preferences.

Protocol
Product Description
PTMScan® HS is an enhanced PTMScan® methodology with improved identification of post-translationally modified peptides. 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 tandem mass spectrometry (LC-MS/MS) for quantitative profiling of post-translational modification (PTM) sites in cellular proteins. PTMs that can be analyzed by PTMScan® technology include phosphorylation, ubiquitination, acetylation, and methylation, among others. The technology enables researchers to isolate, identify, and quantitate large numbers of post-translationally modified cellular peptides with a high degree of specificity and sensitivity (HS), providing a global overview of PTMs in cell and tissue samples without bias about where the modified sites occur.

Background
Acetylation of lysine, like phosphorylation of serine, threonine or tyrosine, is an important reversible modification controlling protein activity. The conserved amino-terminal domains of the four core histones (H2A, H2B, H3, and H4) contain lysines that are acetylated by histone acetyltransferases (HATs) and deacetylated by histone deacetylases (HDACs) (1). Signaling resulting in acetylation/deacetylation of histones, transcription factors, and other proteins affects a diverse array of cellular processes including chromatin structure and gene activity, cell growth, differentiation, and apoptosis (2-6). Recent proteomic surveys suggest that acetylation of lysine residues may be a widespread and important form of post-translational protein modification that affects thousands of proteins involved in control of cell cycle and metabolism, longevity, actin polymerization, and nuclear transport (7,8). The regulation of protein acetylation status is impaired in cancer and polyglutamine diseases (9), and HDACs have become promising targets for anti-cancer drugs currently in development (10).
