MAASTY: a (dis)ordered copolymer for structural determination of human membrane proteins in native nanodiscs.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Amphiphilic copolymers capable of extracting membrane proteins directly from cellular membranes into "native nanodiscs" offer a simplified approach for preparing membrane proteins in lipid nanodiscs compared to approaches that rely on detergent. Copolymer amphiphilicity, length, and composition influence their performance, in addition to the protein itself and the purification conditions used. Here, we report a copolymer composed of methacrylic acid and styrene, which we term MAASTY, leveraging the inherent monomer reactivity ratios to create an anionic copolymer with a statistical distribution of monomers. We show that MAASTY can be used for high-resolution structural determination of a human membrane protein by single particle cryo-electron microscopy, preserving endogenous lipids including cholesterol and exhibiting an enrichment of phosphatidylinositol. Moreover, MAASTY copolymers effectively solubilize a broad range of lipid species and a wide range of different, eukaryotic membrane proteins from mammalian cells. We find that MAASTY copolymers are promising as effective solubilizers of membrane proteins and offer a chemical platform for structural and functional characterization of membrane proteins in native nanodiscs.
