ABSTRACT
Nonsense-mediated RNA decay (NMD) mechanism controls the quality of eukaryotic mRNAs by degradation of aberrant transcripts with a premature stop codon (PTC) in a pioneer round of translation. Besides aberrant transcripts, up to 10% of normal mRNA transcripts can be regulated by NMD. As NMD machinery is associated with translation, this system takes part in proteome formation in eukaryotic cells [1,2]. However, no proteomic datasets of plants with deficient NMD system are currently available. Here, we provide an isobaric tag for relative and absolute quantitation (iTRAQ)-based quantitative proteomic dataset of the moss Physcomitrium patens smg1 knockout line. The kinase SMG1 is one of the key components of the NMD system in many organisms, including plants. 8-day old protonema of wild type and mutant lines was used for the iTRAQ experiment in three biological replicates. LC-MS/MS data were processed using PEAKS Studio v.8 Software with protein identification based on a Phytozome protein database. Differentially expressed protein groups up- and down-regulated in the smg1 knockout line were found in the resulting dataset. Presented data can improve our understanding of NMD functions in plants.
