Abstract

We show that the extent of transcriptional regulation of many, apparently unrelated, genes in Saccharomyces cerevisiae is dependent on RPD1 (and RPD3 [M. Vidal and R. F. Gaber, Mol. Cell. Biol. 11:6317-6327, 1991]). Genes regulated by stimuli as diverse as external signals (PHO5), cell differentiation processes (SPO11 and SPO13), cell type (RME1, FUS1, HO, TY2, STE6, STE3, and BAR1), and genes whose regulatory signals remain unknown (TRK2) depend on RPD1 to achieve maximal states of transcriptional regulation. RPD1 enhances both positive and negative regulation of these genes: in rpd1 delta mutants, higher levels of expression are observed under repression conditions and lower levels are observed under activation conditions. We show that several independent genetic screens, designed to identify yeast transcriptional regulators, have detected the RPD1 locus (also known as SIN3, SD11, and UME4). The inferred RPD1 protein contains four regions predicted to take on helix-loop-helix-like secondary structures and three regions (acidic, glutamine rich, and proline rich) reminiscent of the activating domains of transcriptional activators.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
