Lysine deserts and cullin-RING ligase receptors: Navigating untrodden paths in proteostasis.
Article in iScience, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The ubiquitin-proteasome system (UPS) governs the degradation of proteins by ubiquitinating their lysine residues. Our study focuses on lysine deserts - regions in proteins conspicuously low in lysine residues - in averting ubiquitin-dependent proteolysis. We spotlight the prevalence of lysine deserts among bacteria leveraging the pupylation-dependent proteasomal degradation, and in the UPS of eukaryotes. To further scrutinize this phenomenon, we focused on human receptors VHL and SOCS1 to ascertain if lysine deserts could limit their ubiquitination within the cullin-RING ligase (CRL) complex. Our data indicate that the wild-type and lysine-free variants of VHL and SOCS1 maintain consistent turnover rates, unaltered by CRL-mediated ubiquitination, hinting at a protective mechanism facilitated by lysine deserts. Nonetheless, we noted their ubiquitination at non-lysine sites, alluding to alternative regulation by the UPS. Our research underscores the role of lysine deserts in limiting CRL-mediated ubiquitin tagging while promoting non-lysine ubiquitination, thereby advancing our understanding of proteostasis.
