Structural and functional analysis of a plant nucleolar RNA chaperone-like protein
2023
Overview
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.
