KAP-2, a protein that binds to the H-box in a bean chalcone synthase promoter, is a novel plant transcription factor with sequence identity to the large subunit of human Ku autoantigen.

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
The KAP-2 protein that binds to the H-box (CCTACC) element in the bean CHS15 chalcone synthase promoter was purified, and internal peptide sequence used to design primers leading to the cloning of KAP-2 from bean (Phaseolus vulgaris) and barrel medic (Medicago truncatula). KAP-2 shares sequence similarity to the large subunit of mammalian Ku autoantigen, a protein proposed to be involved in control of DNA recombination and transcription. KAP-2 sequences were present in genomic DNA from a range of legumes, and a related protein is found in Arabidopsis thaliana. Recombinant KAP-2 expressed in insect cells showed the same binding specificity for the CHS15 H-box as the protein purified from bean cell extracts. In vitro transcription assays confirmed that KAP-2 stimulates transcription from a promoter harboring the H-box cis element.
