An article published in the journal “Science” describes a research that states the importance of the mechanism called post-translational modification (PTM) in evolution. An international team led by Pedro Beltrao of the European Molecular Biology Laboratory, European Bioinformatics Institute (EMBL-EBI) and by Professor Judit Villen of the University of Washington investigated in particular phosphorylation obtaining information also useful in medical research such as that on cancer.
