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

The E3 ubiquitin (UB) ligase Parkin utilizes a Ring-Between-Ring (RBR) domain to mediate UB transfer to substrate proteins, and mutations affecting Parkin catalysis promote cancer and are associated with Parkinson's disease. An essential role of Parkin is to initiate mitophagy by ubiquitinating mitochondrial proteins. Still, it is unclear how Parkin carries out other cellular functions, such as the regulation of the cell cycle, metabolism, and the neuronal synapse. Here, we used phage display to engineer the RBR domain of Parkin and assembled an orthogonal ubiquitin transfer (OUT) cascade to profile Parkin substrates in living cells. Guided by the substrate profile from the OUT screen, we verified a panel of Rab GTPases and CDK5 as Parkin substrates. We also showed mitophagy stimulation enhanced Parkin-mediated ubiquitination of Rab proteins. Our work demonstrates that the OUT cascade can be an empowering tool for identifying Parkin substrates to elucidate its multifaceted cellular functions.
