1 · What the graph read from it

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.

2 · The registry

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

Pairing center (PC) on each chromosome of Caenorhabditis elegans is crucial for homolog pairing and initiating synapsis. Within each PC, clusters of 11/12 bp DNA motif recruit one of four paralogous meiosis-specific proteins: ZIM-1, ZIM-2, ZIM-3, or HIM-8. However, the mechanistic basis underlying the specificity of ZIM/HIM-8-PC DNA interaction remains elusive. Here, we describe crystal structures of HIM-8, ZIM-1 and ZIM-2 DNA binding domains (ZF1, ZF2 and CTD) in complex with their cognate PC DNA motifs, respectively. These structures demonstrated the ZF1-2-CTD folds as an integrated structural unit crucial for its DNA binding specificity. Base-specific DNA-contacting residues are exclusively distributed on ZF1-2 and highly conserved. Furthermore, the CTD potentially contributes to the conformational diversity of ZF1-2, imparting binding specificity to distinct PC DNA motifs. These findings shed light on the mechanism governing PC DNA motif recognition by ZIM/HIM-8 proteins, suggesting a co-evolution relationship between PC DNA motifs and ZF1-2-CTD in shaping the specific recognition.
