Efficient termination of vacuolar Rab GTPase signaling requires coordinated action by a GAP and a protein kinase.
Article in The Journal of cell biology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 93 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
Rab guanosine triphosphatases (GTPases) are pivotal regulators of membrane identity and dynamics, but the in vivo pathways that control Rab signaling are poorly defined. Here, we show that the GTPase-activating protein Gyp7 inactivates the yeast vacuole Rab Ypt7 in vivo. To efficiently terminate Ypt7 signaling, Gyp7 requires downstream assistance from an inhibitory casein kinase I, Yck3. Yck3 mediates phosphorylation of at least two Ypt7 signaling targets: a tether, the Vps-C/homotypic fusion and vacuole protein sorting (HOPS) subunit Vps41, and a SNARE, Vam3. Phosphorylation of both substrates is opposed by Ypt7-guanosine triphosphate (GTP). We further demonstrate that Ypt7 binds not one but two Vps-C/HOPS subunits: Vps39, a putative Ypt7 nucleotide exchange factor, and Vps41. Gyp7-stimulated GTP hydrolysis on Ypt7 therefore appears to trigger both passive termination of Ypt7 signaling and active kinase-mediated inhibition of Ypt7's downstream targets. We propose that signal propagation through the Ypt7 pathway is controlled by integrated feedback and feed-forward loops. In this model, Yck3 enforces a requirement for the activated Rab in docking and fusion.
