Bipartite binding of the N terminus of Skp2 to cyclin A.

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
Skp2 and cyclin A are cell-cycle regulators that control the activity of CDK2. Cyclin A acts as an activator and substrate recruitment factor of CDK2, while Skp2 mediates the ubiquitination and subsequent destruction of the CDK inhibitor protein p27. The N terminus of Skp2 can interact directly with cyclin A but is not required for p27 ubiquitination. To gain insight into this poorly understood interaction, we have solved the 3.2 Å X-ray crystal structure of the N terminus of Skp2 bound to cyclin A. The structure reveals a bipartite mode of interaction with two motifs in Skp2 recognizing two discrete surfaces on cyclin A. The uncovered binding mechanism allows for a rationalization of the inhibitory effect of Skp2 on CDK2-cyclin A kinase activity toward the RxL motif containing substrates and raises the possibility that other intermolecular regulators and substrates may use similar non-canonical modes of interaction for cyclin targeting.
