Structural basis to stabilize the domain motion of BARD1-ARD BRCT by CstF50.
Article in Scientific reports, 2017. 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
BRCA1 associated ring domain protein 1(BARD1) is a tumor suppressor protein having a wide role in cellular processes like cell-cycle checkpoint, DNA damage repair and maintenance of genomic integrity. Germ-line mutation Gln 564 His discovered in linker region of BARD1 leads to loss of binding to Cleavage stimulating factor (CstF50), which in turn instigates the premature mRNA transcript formation and apoptosis. We have studied the dynamics of ARD domain present in the BARD1 wild-type and mutant protein in association with CstF50 using biophysical, biochemical and molecular dynamics simulations. It has been observed that the ARD domain is relatively more flexible than the BRCT domain of BARD1. Further relative orientations of both the ARD and BRCT domains varies due to the highly flexible nature of the connecting linker region present between the domains. It has been observed that mutant ARD domain is more dynamic in nature compared to wild-type protein. Molecular docking studies between BARD1 Gln 564 His mutant and CstF50 shows the loss of interactions. Furthermore, domain motion of ARD present in BARD1 was stabilized when complexed with CstF50.
