Discovery of SOCS7 as a versatile E3 ligase for protein-based degraders.
Article in iScience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Targeted protein degradation (TPD) strategy harnesses the ubiquitin-proteasome system (UPS) to degrade a protein of interest (POI) by bringing it into proximity with an E3 ubiquitin ligase. However, the limited availability of functional E3 ligases and the emergence of resistance through mutations in UPS components restrict this approach. Therefore, identifying alternative E3 ligases suitable for TPD is important to develop new degraders and overcome potential resistance mechanisms. Here, we use a protein-based degrader method, by fusing an anti-tag intracellular antibody to an E3 ligase, to screen E3 ligases enabling the degradation of a tagged POI. We identify SOCS7 E3 ligase as effective biodegrader, able to deplete its target in various cell lines regardless of the POI's subcellular localization. We show its utility by generating a SOCS7-based KRAS degrader that inhibits mutant KRAS pancreatic cancer cells' proliferation. These findings highlight SOCS7 versatility as valuable E3 ligase for generating potent degraders.
