The Gcn4 Transcription Factor Reduces Protein Synthesis Capacity and Extends Yeast Lifespan
In Saccharomyces cerevisiae, deletion of genes encoding proteins of the large ribosomal subunit (RPLs) increases the replicative lifespan in a Gcn4-dependent manner. However, how Gcn4, a key transcriptional activator of amino acid biosynthesis genes, increases lifespan, is unknown. Here we show that Gcn4 acts as a repressor of protein synthesis. By analyzing the mRNA and protein abundance, the ribosome occupancy and protein synthesis rate in various yeast strains, we demonstrate that Gcn4 is suf...

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
