Correspondingly, the need to make these data publicly available in centralized online databases has also become more pressing. J Proteome Res. 2012, 16 (1-2): 206-213. The term proteomics was introduced in 1994. Further, the amino acid sequence can be analyzed by programs such as Pfam, Interpro, SMART or also DAVID, to learn if the identified protein shares a specific protein fold with other proteins [39, 66–68]. More. A protein can be involved in mulitiple complexes of varying composition and to completely understand a biological system it is necessary to analyze the abundant protein complexes as well as the conditions that lead to their formation or dissociation. Epub 2010 Jul 6. MS data is analysed to identify and quantify the detected peptides, and assemble it to proteins. Nowadays enrichment analyses are available with almost all pathway database resources, so that a list of significantly altered proteins, with regard to abundance and/or post-translational modifications, is sufficient to extract data on pathway abundance. Can be done on the Maldi-TOF or by LCMS on the QTOF (Synapt G2-Si). Making proteomics data accessible and reusable: current state of proteomics databases and repositories. Nucleic Acids Res. In the future it is very likely that such studies will uncover new principles of how biological systems operate hopefully leading to an improved treatment of human pathologies. To demonstrate the importance of these molecules, Berzelius in 1838 given the title “protein”, which is originated from the Greek word, proteios, meaning “the first rank” (1). 10.1093/nar/gkr988. The tested datasets consisted of core proteins and associated proteins of 5 different pathways, Wnt, App, and Ins signaling, mitochondrial apoptosis as well as tau phosphorylation, respectively, which were retrieved from literature mining and a set of background proteins from proteomic analysis of HEK293 cells that that were falsely annotated as significantly regulated proteins in several repeats. 2002. Cell. A second important choice for the result of GO term enrichment is the reference dataset, which is either predefined by the tool, for instance all genes of the organism, or can be selected manually (all identified proteins) [42]. A final step is then required to assemble the identified peptides into proteins, which can be challenging, in particular when dealing with redundant peptides or alternatively spliced proteins [13]. Huang D, Sherman B, Lempicki R: Systematic and integrative analysis of large gene lists using DAVID bioinformatics resources. The Merck Index* MarinLit. Several enrichment and fractionation steps can be introduced at protein or peptide level in this general workflow when sample complexity has to be reduced or when a specific subset of proteins/peptides should be analysed (i.e. 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. 2005, 4 (10): 1419-1440. This approach is based on a general method called selected reaction monitoring (SRM), where predefined peptides at scheduled RT are selected and fragmented, and two or three fragments monitored.

The first step after GO-term annotation is a GO-term enrichment analysis to compare the abundance of specific GO-terms in the dataset with the natural abundance in the organism or a reference dataset, e.g. Although many of the large databases have been curated throughout the recent years, this can pose quite a bioinformatic challenge and can lead to a substantial loss of information. Based on a iterative strategy of proteomic analysis, data interpretation and sytstematic challenges, hypothesis can be developed and modified, which will eventually lead to the generation of new knowledge (Figure 1). Waegele B, Dunger-Kaltenbach I, Fobo G, Montrone C, Mewes HW, Ruepp A: CRONOS: the cross-reference navigation server. Introduction of the Gene Ontology helped to overcome the redundancy in terminology for biological processes [32]. 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]. These limitations have been successfully addressed by the so-called targeted proteomics [6]. Proteomics. 2013. The authors also mention tissue- or species-specific databases such as the Cardiac Organellar Protein Atlas Knowledgebase (COPaKB) and Pep2Pro (Arabidopsis thaliana), in addition to the iProX database currently in development. On the other hand, the peptide identification is achieved through its fragmentation spectrum. 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. 10.1038/nprot.2010.196.
