About LymPHOS
LymPHOS is a continuously evolving PhosphoProteome DataBase for human T-Lymphocytes. And it is also a Web-Application that allows everyone to freely access all this information from the Internet.
PhosphoProteome
Protein phosphorylation-dephosphorylation events play a primordial role in almost all aspects of cell function including signal transduction, cell cycle and apoptosis. Phosphorylation is probably the most frequent reversible posttranslational modification of proteins (about 30% of the cell proteins are phosphorylated in a given condition). However, the number of known in vivo substrates of kinases is still low.
Where does LymPHOS come from?
LymPHOS data has been obtained at the CSIC/UAB Proteomics Laboratory of the Spanish National Research Council (CSIC), mainly under a Spanish Research Project funded by Research and Education Ministry (BIO2004-01788) during the period 2004-2011. In this project we study, using a proteomic approach, the phosphoproteome of T and B lymphocytes upon (physiological or pharmacological)activation. The main objective was the design of a coherent and comprehensive database of phosphoproteins and phosphorylation sites in these cells. The characterization of phosphorylation motifs will help in the search for new, physiologically relevant kinases as well as in the understanding of the mechanisms involved in the regulation of protein function. This information is the first step towards the design of new therapies based on drugs controlling either kinase/phosphatase activities or the activity of other proteins in key points of the affected pathways.
