Mutagenesis of the cysteine-rich clip domain in the Drosophila patterning protease, Snake.
Article in Archives of biochemistry and biophysics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
A common motif found in invertebrate serine proteases involved in immunity and development is the clip domain, proposed to regulate catalytic activity or protein-protein interactions within proteolytic cascades. Snake functions in a cascade that patterns the Drosophila embryo, and provides an accessible model for exploring the structural requirements for clip domain function. We tested Snake zymogens bearing charged-to-alanine mutations in the clip domain for their ability to rescue embryos lacking endogenous Snake and for their interactions by S2 cell co-transfection with upstream Gastrulation Defective and downstream Easter in the protease cascade. Of 13 single and multiple substitutions, one double mutant in a predicted protruding region exhibited a severe defect in embryonic rescue but showed only minimal defects in the co-transfection assay. We discuss implications of these and other results for potential biological roles of the Snake clip domain and for use of the in vitro assay in predicting protease behavior.
