Molecular mechanism of allosteric activation of the CRISPR ribonuclease Csm6 by cyclic tetra-adenylate.
Article in The EMBO journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Type III CRISPR systems are innate immune systems found in bacteria and archaea, which produce cyclic oligoadenylate (cOA) second messengers in response to viral infections. In these systems, Csm6 proteins serve as ancillary nucleases that degrade single-stranded RNA (ssRNA) upon activation by cOA. In addition, Csm6 proteins also possess cOA-degrading activity as an intrinsic off-switch to avoid degradation of host RNA and DNA that would eventually lead to cell dormancy or cell death. Here, we present the crystal structures of Thermus thermophilus (Tt) Csm6 alone, and in complex with cyclic tetra-adenylate (cA
