TF paralogs-Natural experiments in DNA binding.
Review in Current opinion in structural biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transcription factor (TF) paralogs provide unique insights into how DNA-binding specificity evolves and diversifies. While paralogous TFs share conserved, highly similar DNA-binding domains, they achieve distinct regulatory functions through mechanisms that are now being elucidated. This review examines how sequence variations between paralogs translate into functional diversity, including how mutations distant from the DNA interface can allosterically modulate binding specificity. We focus on competitive binding dynamics when paralogs are co-expressed and discuss emerging evidence that TFs recognize extensive repertoires of lower-affinity binding sites. Differential preferences for lower-affinity binding sites create paralog-specific binding patterns that determine TF genomic occupancy. These insights have important implications for interpreting the impact of coding and noncoding variation on TF-DNA interactions and human disease.
