Characterisation of functional domains in fission yeast Ams2 that are required for core histone gene transcription.

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
Histone gene expression is regulated in a cell cycle-dependent manner, with a peak at S phase, which is crucial for cell division and genome integrity. However, the detailed mechanisms by which expression of histone genes are tightly regulated remain largely unknown. Fission yeast Ams2, a GATA-type zinc finger motif-containing factor, is required for activation of S phase-specific core histone gene transcription. Here we report the molecular characterisation of Ams2. We show that the zinc finger motif in Ams2 is necessary to bind the histone gene promoter region and to activate histone gene transcription. An N-terminal region of Ams2 acts as a self-interaction domain. Intriguingly, N-terminally truncated Ams2 binds to the histone gene promoters, but does not fully activate histone gene transcription. These observations imply that Ams2 self-interactions are required for efficient core histone gene transcription. Moreover, we show that Ams2 interacts with Teb1, which itself binds to the core histone gene promoters. We discuss the relationships between Ams2 domains and efficient transcription of the core histone genes in fission yeast.
