The multifaceted histone chaperone RbAp46/48 in Plasmodium falciparum: structural insights, production, and characterization.
Article in Parasitology research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
RbAp46/RBBP7 and RbAp48/RBBP4 are WD40-repeat histone chaperones and chromatin adaptors that reside in multiple complexes involved in maintenance of chromatin structure. RbAp48 is the essential subunit of the chromatin assembly factor-1 (CAF-1) complex, therefore also named as CAF-1C. A detailed in silico sequence and structure analysis of homologs of RbAp46/48 in Plasmodium falciparum (PF3D7_0110700 and PF3D7_1433300) exhibited conservation of characteristic features in both the protein-seven-bladed WD40 β-propeller conformation and different binding interfaces. A comparative structural analysis highlighted species-specific features of the parasite, yeast, drosophila, and human RbAp46/48. In the present study, we report cloning, expression, and characterization of P. falciparum PF3D7_0110700, a putative RbAp46/48 (PfRbAp46/48). PfRbAp46/48 was cloned into pTEM11 vector in fusion with 6xHistidine tag and over-expressed in Escherichia coli B834 cells. The protein was purified by Ni-NTA followed by gel permeation chromatography. The protein expressed in all the three asexual blood stages and exhibited nuclear localization. We showed direct interaction of the purified rPfRbAp46/48 with the histone H4. These findings further our understanding of RbAp46/48 proteins and role of these proteins in the parasite biology.
