We describe an integrated proteome database, termed Yonsei Proteome Research Center Proteome Database (YPRC-PDB) which can store, retrieve and analyze various information including two-dimensional electrophoresis (2-DE) images and associated spot information that were obtained during studies of hepa … An integrated proteome database for two-dimensional electrophoresis data analysis … 10.1093/nar/gkn892. It is an important component of functional genomics. The obtained results showed a rather high discrepancy for p-values of certain GO terms . Proteins are subjected to a constant turnover making protein homeostasis a very important feature of their regulation. Protein analysis and, more specifically, proteomics have driven the development of mass spectrometry for the past decade.

Recently, EnrichNet was launched, a web-based platform integrating pathway and interaction analysis in 6 different databases (KeGG, BioCarta, Gene Ontology, Reactome, Wiki and NCI pathways) with functional associations and connecting these data with molecular function (Interpro) and protein complex information (Corum) . PloS one. 10.1093/nar/28.18.3442. By using this dynamic exclusion , less abundant peptides are also selected for fragmentation. : The Proteomics Identifications (PRIDE) database and associated tools: status in 2013. 2012, 41 (D1): D1063-D1069. This course is oriented towards biologists and bioinformaticians with a particular interest in differential analysis for quantitative proteomics. 10.1093/nar/gkr931. 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. 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. The AUC of the monitored fragments can then be used for quantification.

With the advent of more powerful and sensitive analytical techniques and instruments, the field of mass spectrometry based proteomics has seen a considerable increase in the amount of generated data. Correspondingly, the need to make these data publicly available in centralized online databases has also become more pressing. 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. 4. to study the structure and function of protein To study the 3D structure of protein … Cell.

Apart from the comprehensive resources, highly specific databases have been developed for signal transduction processes such as PANTHER, GenMAPP or PID [48–50]. The term proteomics was introduced in 1994. Weinert et al. 2006. Proteomics data repositories: providing a safe haven for your data and acting as a springboard for further research. 2013 Oct 15;29(20):2661-3. doi: 10.1093/bioinformatics/btt437. Chemistry World. PubMed Nat Biotech. 2009, 9 (2): 761-776. The multiplexing capability have been used to quantify several hundreds of proteins in a broad dynamic range, down to proteins present at very low copy number in the cell (~50 copies/cell) in the background of the whole range of protein concentration in eukaryotic cells [18, 19]. 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 . 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) .
