Functionality

  • Proteoform Identification: Proteoform are identified from measurements of intact mass and optionally lysine count.
  • Custom Database: PTMs archived and UniProt and discovered using G-PTM-D or MetaMopheus are used in the construction of theoretical proteoforms.
  • Quantification: NeuCode-labeled or unlabeled proteoform intensity ratios are calculated from separate analysis files following proteoform identification.
  • Gene Ontology Analysis: Performed alongside quantification based on proteoforms that are significantly induced or repressed. GO terms are obtained from UniProt protein annotations.
  • Visualization: ProteoformSuite facilitates the visualization of the relationships between proteoforms by creating scripts to load in the network visualization program Cytoscape.

Requirements

The following files must be obtained and installed:
