For this purpose, a variety of literature mining tools to screen PubMed abstracts has been developed of which chilibot and sciminer are most favored [60, 61]. Apart from the comprehensive resources, highly specific databases have been developed for signal transduction processes such as PANTHER, GenMAPP or PID [48–50]. Proteomics. Proteomics • The analysis of the entire protein complement in a given cell, tissue, body fluid and organism • Proteomics assesses activities, modifications, localization, and interactions of proteins in complexes. For larger data sets and sytstematic approaches some database search algorithms for proteomic data such as MaxQuant, Proteome Discoverer and X!tandem [34, 35] have implemented a GO-term annotation step. The Proteomics Identifications database (PRIDE) (http://www.ebi.ac.uk/pride) was developed at the European Bioinformatics Institute (EBI), as a repository for the results of MS-based proteomics experiments, allowing data from a vast range of approaches, instruments and analysis platforms to be stored and disseminated in a common structured and queryable format. 10.1093/nar/28.18.3442.

Bates et al. Nucleic Acids Res. 2006. Most biochemical reactions in a cell are regulated by highly specialized proteins, which are the prime mediators of the cellular phenotype. More sophisticated algorithms are gene set enrichment algorithms (GSEA) that take all genes of analysis into account, not only gene with significant change of abundance. Proteins are synthesized by translating the information encoded in a RNA molecule to a polypeptide chain, which adopts a specific three dimensional structure. The output of a proteome analysis either in a shotgun approach or a more targeted method is usually a long list of identified factors, that have a probability score and ideally also a quantitative value associated with them.  |  The proteomics results showed that 526 proteins have significant changes in abundance between control and H 2 S treated swine. In case of the proteomic investigation, the challenges occur at all levels ranging from sample preparation and data gathering over the raw data integration and database searching to the functional interpretation of large datasets. 10.1038/nbt.1511. 2013, 494 (7436): 266-270. 10.1093/nar/gks338. Bioinformatics (Oxford, England). PubMed  Briefly, search algorithms aim to explain a recorded MS2 spectrum by a peptide sequence from a pre-defined database, returning a list of peptide sequences that fit to the experimental data with a certain probability score or false discovery rate (FDR).
