Function of the N-terminal segment of the RecA-dependent nuclease Ref.
Article in Nucleic acids research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The bacteriophage P1 Ref (recombination enhancement function) protein is a RecA-dependent, HNH endonuclease. It can be directed to create targeted double-strand breaks within a displacement loop formed by RecA. The 76 amino acid N-terminal region of Ref is positively charged (25/76 amino acid residues) and inherently unstructured in solution. Our investigation of N-terminal truncation variants shows this region is required for DNA binding, contains a Cys involved in incidental dimerization and is necessary for efficient Ref-mediated DNA cleavage. Specifically, Ref N-terminal truncation variants lacking between 21 and 47 amino acids are more effective RecA-mediated targeting nucleases. We propose a more refined set of options for the Ref-mediated cleavage mechanism, featuring the N-terminal region as an anchor for at least one of the DNA strand cleavage events.
