Lay Summary (English)

Lay summary
This proposal is a direct continuation of project 200020-105489/1 that had a two-fold objective: first, to develop proteome fractionation tools based on isoelectric focusing, and second, to develop tagging strategies to increase the information content of mass spectrometric experiment. This proposal follows the same line of research on a more focused target: phosphoproteome analysis. Protein phosphorylation plays a crucial role in many biological processes, such as signal transduction through protein kinase cascades, gene regulation through enzyme activation / inhibition, cytoskeletal activation… Whereas phosphorylation has been the most studied protein post-translational modification so far, all available technologies or methodologies present serious caveats. The gist of this proposal is to develop new tools for proteome fractionation based on isoelectric focusing, and phosphoproteome targeting, isolation and analysis based on metallic ligands.
