Chromatin-bound U2AF2 splicing factor ensures exon inclusion.
Article in Molecular cell, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Most mRNA splicing occurs co-transcriptionally, but it is unclear how splicing factors accurately select exons for inclusion. Using CUT&RUN profiling in K562 cells, we demonstrate that three splicing factors-SF3B1, U2AF1, and U2AF2-bind near active promoters of intron-containing and intronless genes, implying their association with the general transcriptional machinery. RNase A treatment reduces factor binding at promoters, indicating that these proteins interact with nascent transcripts. Strikingly, the U2AF2 protein also accumulates throughout intron-containing gene bodies and requires histone H3-lysine36 trimethylation but not nascent transcripts or persistent RNA polymerase II. Chromatin-bound U2AF2 preferentially binds to exons of highly expressed, exon-dense genes, with greater occupancy at exons skipped after U2AF2 knockdown, suggesting that U2AF2 enhances exon selection accuracy. U2AF2-targeted genes include those encoding splicing factors, where it improves splicing accuracy and efficiency. Our findings provide a mechanistic basis for the homeostatic regulation of efficient co-transcriptional splicing by chromatin-bound U2AF2.
