CCSer2 gates dynein activity at the cell periphery.
Article in The Journal of cell biology, 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
Cytoplasmic dynein-1 (dynein) is a microtubule-associated, minus end-directed motor that traffics hundreds of different cargos. Dynein must discriminate between cargos and traffic them at the appropriate time from the correct cellular region. How dynein's trafficking activity is regulated in time or cellular space remains poorly understood. Here, we identify CCSer2 as the first known protein to gate dynein activity in the spatial dimension. CCSer2 promotes the migration of developing zebrafish primordium cells, macrophages, and cultured human cells by facilitating the trafficking of cargos that are acted on by peripherally localized dynein. Our data suggest that CCSer2 disfavors the interaction between dynein and its regulator Ndel1 at the cell edge, resulting in localized dynein activation. These findings support a model where the spatial specificity of dynein is achieved by the localization of proteins that trigger Ndel1's release from dynein. We propose that CCSer2 defines a broader class of proteins that activate dynein in distinct microenvironments via regulating Ndel1-dynein interaction.
