Structural dynamics of mixed-subunit CaMKIIα/β heterododecamers filmed by high-speed AFM.
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 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
CaMKII predominantly assembles into a 12-meric ring assembly, primarily consisting of α and β isoforms in the brain. Previous biochemical studies reported varying ratios of these CaMKII variants across different brain regions and developmental stages. However, direct evidence for the formation of CaMKIIα/β heterooligomers within a 12-meric ring assembly has been lacking at the single-molecule level. Here, we employ high-speed atomic force microscopy to visualize the conformational dynamics of forebrain-mimicked CaMKIIα/β at a 3:1 ratio. Our findings reveal that the α and β subunits are intermixed within the 12-meric ring assembly, with a probability exceeding 83% that β subunits are positioned adjacently. Furthermore, in the activated state, CaMKIIα/β heterooligomers form a stable kinase domain complex via interactions between adjacent CaMKIIβ subunits, resulting in a long-lasting structure with an exposed target binding site. Collectively, our observations provide insights into the structural role of CaMKIIβ subunits within the CaMKIIα/β heterododecamer.
