An ATPase activity associated with the rotavirus phosphoprotein NSP5.
Article in Virology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Interactions between NSP5 and NSP2 drive the formation of viroplasms, sites of genome replication and packaging in rotavirus-infected cells. The serine-threonine-rich NSP5 transitions between hypo- and hyper-phosphorylated isomers during the replication cycle. In this study, we determined that purified recombinant NSP5 has a Mg2+-dependent ATP-specific triphosphatase activity that generates free ADP and Pi (Vmax of 19.33 fmol of product/min/pmol of enzyme). The ATPase activity was correlated with low levels of NSP5 phosphorylation, suggestive of a possible link between ATP hydrolysis and an NSP5 autokinase activity. Mutagenesis showed that the critical residue (Ser67) needed for NSP5 hyperphosphorylation by cellular casein kinase-like enzymes has no role in the ATPase or autokinase activities of NSP5. Through its NDP kinase activity, the NSP2 octamer may support NSP5 phosphorylation by creating a constant source of ATP molecules for the autokinase activity of NSP5 and for cellular kinases associated with NSP5.
