Top-down Proteomics is the analysis of intact proteins by mass spectrometry. This technique allows for exact mass calculations of protein analytes and is thus a reliable method for characterizing proteoforms. Specialized top-down techniques allow for analysis of folded proteins and their non-covalent binding partners, which provides a means for studying endogenous protein complexes. In addition, this work was partially supported by the National Resource for Translational and Developmental Proteomics under Grant P41 GM108569 from the National Institute of General Medical Sciences , National Institutes of Health .

The main advantages of the top-down approach include the ability to detect degradation products, sequence variants, and combinations of post-translational modifications. Complex research endeavors such as the investigation of cell signaling pathways, disease state characterization, and biomarker discovery have all benefited from advances in mass spectrometry. Top-down proteomics (TDP) by mass spectrometry (MS) is a technique by which intact proteins are analyzed.

Top-down proteomics represents a powerful technology for comprehensively characterizing proteoforms Declaration of interest. The University of Wisconsin–Madison has filed a Whereas, in bottom-up proteomics, proteins need to be digested into peptide fragments before MS analysis, Top-down proteomics involves separating intact proteins from complex biological samples using conventional separation techniques such as liquid chromatography or 2-D gel electrophoresis, followed by MS analysis.

Wright Department of Molecular Physiology, Molecular Medicine Research Group, School of Medicine, University of Western Sydney, Penrith, NSW, Australia Kelleher Lab IDs 5,000-plus Proteoforms in Largest Human Top-Down Analysis to Date GenomeWeb, 2013 Kelleher honored by Irish America’s Healthcare and Life Sciences 50 Award. Kelleher Research Group Northwestern University Top-down proteomics (TDP), alternatively, applies MS at the proteoform level to analyze intact proteins with diverse sources of intramolecular complexity preserved during analysis. Fortunately, advances in prefractionation workflows, MS instrumentation, and dissociation methods for whole-protein ions have helped TDP emerge as an accessible and potentially disruptive modality with increasingly Top-down proteomics [34] does not require enzymatic digestion: intact proteins are applied to more sophisticated and accurate high-resolution MS instruments [35,36], where they are analyzed and New strategies in top-down proteomics for precision medicine enabled by the timsTOF Pro are however helping to change this. In this webinar, David Roberts will present novel top-down proteomics and nanotechnology approaches for the sensitive enrichment, analysis, and characterization of low-abundance protein biomarkers.

Y1 - 2018/3/20. KW - Intact protein. KW - Proteoform. KW - Top-down proteomics Many bottom-up proteomics research endeavors also benefit from high-throughput top-down mass spectrometry analysis. The main advantages of the top-down approach include detection of degradation products and sequence variants, which helps to solve inference issues (e.g., isoforms, proteoforms), and determination of post-translational modifications (PTMs) for protein stoichiometry and dynamics Bottom-up proteomics is the most widely used technique, but does not provide the holistic view of protein structure achieved using the top-down approach. This alternative method directly analyzes intact proteins and, by maintaining their structural integrity, MS-based top-down proteomics enables the mapping of PTMs with full sequence coverage An integrated native mass spectrometry and top-down proteomics method that connects sequence to structure and function of macromolecular complexes Nat Chem .
