UbFluor: A Fluorescent Thioester to Monitor HECT E3 Ligase Catalysis.
Article in Current protocols in chemical biology, 2017. 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
HECT E3 ubiquitin ligases (∼28 are known) are associated with many phenotypes in eukaryotes and are important drug targets. However, assays used to screen for small molecule inhibitors of HECT E3s are complex and require ATP, Ub, E1, E2, and HECT E3 enzymes, producing three covalent thioester enzyme intermediates E1∼Ub, E2∼Ub, and HECT E3∼Ub (where ∼ indicates a thioester bond), and mixtures of polyubiquitin chains. To reduce the complexity of the assay, we developed a novel class of fluorescent probes, UbFluor, that act as mechanistically relevant pseudosubstrates of HECT E3s. These probes undergo a direct transthiolation reaction with the catalytic cysteine of HECT E3s, producing the catalytically active HECT E3∼Ub thioester accompanied by fluorophore release. Thus, a fluorescence polarization assay can continuously monitor UbFluor consumption by HECT E3s, and changes in UbFluor consumption rendered by biochemical point mutations or small molecule modulation of HECT E3 activity. © 2017 by John Wiley & Sons, Inc.
