The influence of genomic variation on protein phosphorylation states and regulatory networks

A scientific evaluation of how genetic variation in a yeast cross impacts the transcriptome, the proteome and the phosphoproteome reveals multi-layered adjustments in regulatory networks that finally have an effect on lots of of mobile traits.


Genomic variation impacts on mobile networks by affecting the abundance (e.g., protein ranges) and the purposeful states (e.g., protein phosphorylation) of their parts. Earlier work has targeted on the previous, whereas on this context, the purposeful states of proteins have largely remained uncared for. Right here, we generated high-quality transcriptome, proteome, and phosphoproteome information for a panel of 112 genomically well-defined yeast strains. Genetic results on transcripts have been usually transmitted to the protein layer, however particular gene teams, comparable to ribosomal proteins, confirmed diverging results on protein ranges in contrast with RNA ranges. Phosphorylation states proved essential to unravel genetic results on signaling networks. Correspondingly, genetic variants that trigger phosphorylation adjustments have been largely completely different from these inflicting abundance adjustments within the respective proteins. Underscoring their relevance for cell physiology, phosphorylation traits have been extra strongly correlated with cell physiological traits comparable to chemical compound resistance or cell morphology, in contrast with transcript or protein abundance. This research demonstrates how molecular networks mediate the consequences of genomic variants to mobile traits and highlights the actual significance of protein phosphorylation.
