Identification of Interacting Motifs Between Armadillo Repeat Containing 1 (ARC1) and Exocyst 70 A1 (Exo70A1) Proteins in Brassica oleracea.
Article in The protein journal, 2016. 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
In order to identify the functional domains which regulate the interaction between the self-incompatibility proteins armadillo repeat containing 1 (ARC1) and exocyst 70 A1 (Exo70A1) in Brassica oleracea, fragments containing selected motifs of ARC1 (ARC1210, ARC1246, ARC1279, ARC1354) and site-specific mutants with substitutions at possible interaction sites (ARC1354m, ARC1664m) were PCR amplified and inserted into pGADT7, while coding sequences from Exo70A1 (Exo70A185, Exo70A1) were subcloned into pGBKT7. The interactions between the protein products produced by these constructs were then analyzed utilizing a yeast two-hybrid system. Our data indicate that both ARC1210 and ARC1246 interact strongly with Exo70A185 and Exo70A1, while ARC1279, ARC1354, ARC1354m and ARC1664m exhibited a weak interaction, indicating that the recognition sites are located within the 210 N-terminal amino acids of ARC1 and the 85 N-terminal amino acids of Exo70A1. This was further verified by GST pull-down analysis. This supports a model in which the N-terminal leucine zipper of ARC1 and the first 85 N-terminal amino acids of Exo70A1 mediate the interaction between these two proteins. Bioinformatic and phylogenetic analysis demonstrated that these motifs were highly conserved across different species, indicating that the interaction characterized in B. oleracea may operate in a wide array of cultivars.
