With knowledge of the wide functional range of phosphorylation, we attempted to clarify whether the evolutionary conservation of phosphosites is different among distinct functional modules. We grouped the phosphosites in the human genome into modules according to the functional categories of KEGG, and we investigated their evolutionary conservation in several vertebrate genomes from mouse to zebrafish. We found that phosphosites in the basic functional modules (BFMs) such as metabolic and genetic processes, display a lower evolutionary conservation than those in the vertebrate-specific functional modules (VFMs) such as signaling processes and more complex organic systems. The phosphosites in the VFMs are also significantly more conserved than their flanking regions, but those in the BFMs are not. The above results hold for both serine/threonine and tyrosine residues, although the fraction of phosphorylated tyrosine is raised in the VFMs. Moreover, the difference in evolutionary conservation of the phosphosites cannot be explained by their difference in local protein structures, and there are also more phosphosites with known functions in the VFMs. Based on these results, we concluded that protein phosphorylation may play more dominant roles for the VFMs than the BFMs. As phosphorylation is a quite rapid biological reaction, the VFMs that quickly respond to outer stimuli and inner signals might more heavily depend on this regulatory mechanism. Our results imply that phosphorylation may have an essential role in the evolution of vertebrates. Resume: Yi-Xue Li was born in Xinjiang, China. Currently, he is vice Director and a full research professor of Key Laboratory of Systems Biology at Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Director in Shanghai Center for Bioinformation Technology, Dean of Department of Bioinformatics and Biostatistics, Shanghai Jiaotong University. Dr. Li received his BSc. and Msc. degrees in theoretical physics from Xinjiang University, China, in 1982 and 1987, respectively, and his Ph.D. degree in theoretical physics from Heidelberg University, Germany in 1996. After Dr. Li got his Ph.D. degree he worked as a bioinformatics research staff in European Molecular Biology Laboratory (EMBL) from 1997-2000, and came back to Shanghai, China in the middle of 2000. Dr. Li has published more than 100 journal papers published in various international scientific journals, such as Science, Nature Genetics, Nature Biotechnology, PNAS, Bioinformatics, NAR, Plos Computational Biology, Plos One, Molecular Systems Biology, Molecular Biology and Evolution, Molecular Cellular Proteomics, Oncogene, BMC Bioinformatics, Genome Biology, etc., and his research results have been cited by more than 1500 researchers worldwide in books, theses, journal and conference papers. He has served as a reviewer/panelist for many national research foundations/agencies such as the Chinese National Science Foundation, the National High-Tech Program(863) and National Key Basic Research Program(973).
