Surveillance of 3' mRNA cleavage during transcription termination requires CF IB/Hrp1.
Article in Nucleic acids research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
CF IB/Hrp1 is part of the cleavage and polyadenylation factor (CPF) and cleavage factor (CF) complex (CPF-CF), which is responsible for 3' cleavage and maturation of pre-mRNAs. Although Hrp1 supports this process, its presence is not essential for the cleavage event. Here, we show that the main function of Hrp1 in the CPF-CF complex is the nuclear mRNA quality control of proper 3' cleavage. As such, Hrp1 acts as a nuclear mRNA retention factor that hinders transcripts from leaving the nucleus until processing is completed. Only after proper 3' cleavage, which is sensed through contacting Rna14, Hrp1 recruits the export receptor Mex67, allowing nuclear export. Consequently, its absence results in the leakage of elongated mRNAs into the cytoplasm. If cleavage is defective, the presence of Hrp1 on the mRNA retains these elongated transcripts until they are eliminated by the nuclear exosome. Together, we identify Hrp1 as the key quality control factor for 3' cleavage.
