Evidence for Functionality of Transmembrane Domains of Predicted Non-Canonical Plant Phosphotransmitters.

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
Bioinformatic methods have been used to predict a new subclass of proteins among plant phosphotransmitters involved in the signaling system of multistep phosphorelay. In contrast to the canonical soluble nucleocytosolic forms, the found noncanonical phosphotransmitter sequences, belonging to a wide range of plant taxa, potentially contain transmembrane domains. This suggests localization of such proteins on cell membranes and, therefore, a different function in signaling than that of canonical phosphotransmitters. We tested the functionality of the transmembrane domain of the phosphotransmitter using the protein of the tea plant Camellia sinensis. The membrane localization of the transiently expressed recombinant phosphotransmitter with this domain was confirmed by microscopy and immunoblotting. Thus, this is the first study to obtain experimental evidence for the existence of membrane-bound plant phosphotransmitters with as yet unknown functions. These data suggest the presence of a noncanonical membrane branch of signal transduction in the multistep phosphorelay system in plants.
