Wright Department of Molecular Physiology, Molecular Medicine Research Group, School of Medicine, University of Western Sydney, Penrith, NSW, Australia Top-down proteomics for the analysis of proteolytic events - Methods, applications and perspectives. Biochimica et Biophysica Acta (BBA) - Molecular Cell Research 2017 , 1864 (11) , 2191-2199. Having grown beyond early ‘proof-of-principle’ studies, top-down proteomics is now extensively used to analyze intact proteins in numerous applications. Here, we discuss how the top-down proteomics approach emerged, reasons underpinning its success, and highlight some of the most exciting current developments.
Top-down proteomics will help identify the proteoforms. The three pillar technologies in top-down proteomics are separation, mass spectrometry and bioinformatics from the point of view on the entire proteins. Summary.

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. Top-down mass spectrometry (MS) analyzes intact proteins at the proteoform level, which allows researchers to better understand the functions of protein modifications. Recently, top-down proteomics has increased in popularity due to advancements in high-resolution mass spectrometers, increased efficiency in Top-down proteomics reveals a unique protein S-thiolation switch in Salmonella Typhimurium in response to infection-like conditions Charles Ansonga,1,2,SiWub,1, Da Mengc, Xiaowen Liud,e, Heather M. Brewerb, Brooke L. Deatherage Kaisera, 26 Feb 2019 In top-down proteomics, intact proteins are introduced to the mass spectrometer where entire and fragmented ion masses are measured. 29 Jan 2019 “Top-down” is the term used to describe an alternative proteomics approach, where proteins are not enzymatically digested into peptides.

TopPIC (TOP-Down Mass Spectrometry Based Proteoform Identification and Characterization) is a software tool for identification and characterization of proteoforms at the whole proteome level by top-down tandem mass spectra using database search.

top down proteomics involves identifying proteins in complex mixtures without prior digestion into their corresponding peptide species. The schematic workflow for top-down proteomics, including protein separation, mass spectrometer detection, and data analysis.

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 .

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 . 2018 Feb;10(2):139-148. doi: 10.1038/nchem.2908. Azo-aided top-down proteomics enables the solubilization of membrane proteins for comprehensive characterization of post-translational modifications.
