1 · What the graph read from it

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.

2 · The registry

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

Linear ubiquitin (Ub) chains regulate many cellular processes, including NF-κB immune signalling. Pathogenic bacteria have evolved to secrete effector proteins that harbour deubiquitinase activity into host cells to disrupt host ubiquitination signalling. All previously identified effector deubiquitinases hydrolyse isopeptide-linked polyubiquitin (polyUb). It has been a long-standing question whether bacterial pathogens have evolved an effector deubiquitinase to directly cleave linear Ub chains. In this study, we performed extensive screening of bacterial pathogens and found that Legionella pneumophila-the causative agent of human Legionnaire's disease-encodes an effector protein, RavD, which harbours deubiquitinase activity exquisitely specific for linear Ub chains. RavD hydrolyses linear Ub chains but not any type of isopeptide-linked polyUb. The crystal structure of RavD with linear diubiquitin reveals that RavD adopts a papain-like fold with a Cys-His-Ser catalytic triad. The Ub-binding surface and specific interacting residues in RavD determine its specificity for Met1 linkages. RavD prevents the accumulation of linear Ub chains on Legionella-containing vacuoles established by the pathogen in host cells to inhibit the NF-κB pathway during infection. This study identified a unique linear Ub chain-specific effector deubiquitinase and indicates its potential application as a tool to dissect linear polyUb-mediated signalling in mammalian cells.
