CaMK IV phosphorylates prohibitin 2 and regulates prohibitin 2-mediated repression of MEF2 transcription.

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
Prohibitin 2 (PHB2) is an evolutionarily conserved and ubiquitously expressed multifunctional protein which is present in various cellular compartments including the nucleus. However, mechanisms underlying various functions of PHB2 are not fully explored yet. Previously we showed that PHB2 interacts with Akt and inhibits muscle differentiation by repressing the transcriptional activity of both MyoD and MEF2. Here we show that Calcium/Calmodulin-dependent kinase IV (CaMK IV) specifically binds to the C terminus of PHB2 and phosphorylates PHB2 at serine 91. Ectopic expression of CaMK IV and PHB2 in C2C12 cells results effectively in decreased PHB2-mediated repression of MEF2-dependent gene expression. Conversely, PHB2 mutant (S91A) resistant to CaMK IV phosphorylation has less effective in relieving the inhibition of MEF2 transcription by PHB2. Our findings suggest that CaMK IV interacts with and regulates PHB2 through phosphorylation, which could be one of the mechanisms underlying the CaMK-mediated activation of MEF2.
