Title	mTPP of temperature sensitive proteasome mutants
Description	Temperature sensitive (TS) missense mutants have been foundational in the characterization essential gene function. However, an unbiased approach for the analysis of the biochemical and biophysical changes in TS missense mutants within the context of their functional proteomes is lacking. We applied mass spectrometry (MS) based thermal proteome profiling (TPP) to investigate the proteome-wide effects of missense mutations in a specific application that we refer to as mutant Thermal Proteome Profiling (mTPP). This study characterized the global changes in mRNA abundance, protein abundance, and protein thermal stability as a result of missense mutants within two subunits of the yeast ubiquitin-proteasome system. Global protein abundance measurements and RNA sequencing data resulted in a large number of possible candidates that could be causing the phenotypic changes observed in the mutant strains. The additional information gained from mTPP along with complementary proteomic and transcriptomic experiments allows for multiomic intersection analysis that may reveal interesting regulatory categories to pursue in follow-up mechanistic experiments.
