The proteome landscape of genome-wide genetic perturbations


ABSTRACT: Despite the massive research efforts of the post-genomics era, a significant fraction of genes remain without functional annotation. Proteomics holds the promise to close significant gaps, but has only recently reached the scalability and precision of genome-scale studies. Here we combine large-scale proteomics with functional genomics and use a streamlined platform for fast yeast proteomics to record quantitative proteomes of ~4,500 single knock-out strains of a genome-scale yeast knock-out collection.

Functional genomic strategies have become fundamental for annotating gene function and regulatory networks. Here, we combined functional genomics with proteomics by quantifying protein abundances in a genome-scale knockout library in Saccharomyces cerevisiae, using data-independent acquisition mass spectrometry. We find that global protein expression is driven by a complex interplay of (1) general biological properties, including translation rate, protein turnover, the formation of protein compl  ...[more]
