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.},
