Genetic interactions between an RNA polymerase II phosphatase and centromeric elements in Saccharomyces cerevisiae.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Saccharomyces cerevisiase protein phosphatase Fcp1 has been implicated in the regulation of transcription by RNA polymerase II, and is encoded by the essential gene FCP1. A screen was carried out for multicopy suppressors of the temperature-sensitive phenotype of two phosphatase mutants, fcp1-2 and fcp1-4. Only the wild-type FCP1 was found to suppress (complement) the fcp1-4 mutation. For fcp1-2 three second-site suppressors were identified. One contained the ORF for ZDS1. The remaining two suppressors mapped to the centromere regions of chromosomes I and V. Suppression due to centromere DNA was found to be more dependent on the CDEIII region than on other regions of the centromere. The presence of a suppressor centromere affected the level of Fcp1 protein and the overall phosphorylation state of RNA polymerase II (RNAPII) in fcp1-2 cells, but not wild-type cells, grown at both permissive and non-permissive temperatures. In addition, genetic interactions were identified between this FCP1 mutant and the genes SKP1, CEP3 and CBF1, which code for centromere binding proteins. The mechanism of suppression and regulation of Fcp1-2 protein activity by centromeric DNA is discussed.
