SUMO-ID: A Strategy for the Identification of SUMO-Dependent Proximal Interactors.
Article in Methods in molecular biology (Clifton, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Posttranslational modifications by the ubiquitin-like family (UbL) of proteins determine the biological fate of a substrate, including new interaction partners. In the case of the small ubiquitin-like modifier (SUMO), this is achieved in part through its non-covalent interaction with SUMO-interacting motifs (SIMs) found in some proteins. Investigating such partner-complex formation is particularly challenging due to the fast dynamics and reversibility of SUMO modifications and the low affinity of SUMO-SIM interactions. Here, we present a detailed protocol of SUMO-ID, a technology that merges promiscuous proximity biotinylation by TurboID enzyme and protein-fragment complementation strategy to specifically biotinylate SUMO-dependent interactors of particular substrates. When coupled to streptavidin-affinity purification and mass spectrometry, SUMO-ID efficiently identifies SUMO-dependent interactors of a given protein. The methodology describes all the steps from SUMO-ID cell line generation to LC-MS sample preparation to study SUMO-dependent interactors of a particular protein. The protocol is generic and therefore adaptable to study other UbL-dependent interactors, such as ubiquitin.
