Structural and functional analysis of a plant nucleolar RNA chaperone-like protein.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Ribosome biogenesis is a key process in all eukaryotic cells that requires hundreds of ribosome biogenesis factors (RBFs), which are essential to build the mature ribosomes consisting of proteins and rRNAs. The processing of the required rRNAs has been studied extensively in yeast and mammals, but in plants much is still unknown. In this study, we focused on a RBF from A. thaliana that we named NUCLEOLAR RNA CHAPERONE-LIKE 1 (NURC1). NURC1 was localized in the nucleolus of plant cell nuclei, and other plant RBF candidates shared the same localization. SEC-SAXS experiments revealed that NURC1 has an elongated and flexible structure. In addition, SEC-MALLS experiments confirmed that NURC1 was present in its monomeric form with a molecular weight of around 28 kDa. RNA binding was assessed by performing microscale thermophoresis with the Arabidopsis internal transcribed spacer 2 (ITS2) of the polycistronic pre-rRNA precursor, which contains the 5.8S, 18S, and 25S rRNA. NURC1 showed binding activity to the ITS2 with a dissociation constant of 228 nM and exhibited RNA chaperone-like activity. Our data suggested that NURC1 may have a function in pre-rRNA processing and thus ribosome biogenesis.
