Posttranslational modifications (PTMs) of proteins represent fascinating extensions of the dynamic complexity of living cells' proteomes, but also present a solid obstacle in the proteome analysis. Identification and mapping of PTMs in proteins have improved dramatically, but to comprehend complex mechanisms and biological functions, one must address also a very low abundant proteins. Here, in this thesis entitled 'Analysis of DELLA protein ubiquitination' we demonstrate the use of a recombinant protein standard for the determination of in vivo modified peptides of the DELLA family protein RGA. The candidate peptide sequences were targeted in an SRM-based analysis to detect the ubiquitination site and the results of this analysis and that of an MS/MS data processing indicate that the modification is localized in the conserved N-terminal region of RGA protein.
