Phase separation instead of binding strength determines target specificities of MAGUKs.
Article in Nature chemical biology, 2026. 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
Homologous proteins often have distinct functions, even if they share overlapping binding targets. PSD-95 and MAGI-2, two membrane-associated guanylate kinase (MAGUK)-family scaffolds in neuronal synapses, exemplify this. With unknown mechanisms, the two MAGUKs are localized at distinct subsynaptic compartments with PSD-95 inside the postsynaptic density (PSD) and MAGI-2 outside. Here we demonstrate that MAGI-2 forms condensates through phase separation. When coexisting with PSD proteins, the MAGI-2 condensate can enrich the extrasynaptic N-cadherin-β-catenin adhesion complex and the MAGI-2 condensates are immiscible with the PSD-95 condensates. Surprisingly, phosphorylated SAPAP is selectively enriched in the PSD-95 condensate, even though it binds to MAGI-2 with a higher affinity. The specific localization of SAPAP is because of the higher network complexities of the PSD-95-containing condensate than the MAGI-2 condensate. Thus, phase-separation-mediated molecular condensate formation can generate a previously unrecognized mode of molecular interaction and subcellular localization specificities that do not occur in dilute solutions.
