Improved algorithms and tools for the identification of novel proteoforms using top-down proteomics
Implementation of sensitive and specific protein species identification and characterization for targeted and untargeted proteomics study by leveraging recently introduced mass deconvolution algorithms. Application of the developed algorithm to reveal novel proteoforms.
Both algorithmic and machine learning-based approaches will be applied for an efficient and sensitive proteoform identification method. The developed algorithm will be used in a stand-alone tool as well as in an interactive visualization tool. The algorithm also could be embedded in instruments for better data acquisition. The development will be performed as part of OpenMS the major C++ open-source framework for computational proteomics.
