ProteomicsRbp95 binds 25S rRNA helix H95 and cooperates with the Npa1 complex during early pre-60S particle maturation
Eukaryotic ribosome synthesis involves more than 200 assembly factors, which promote ribosomal RNA (rRNA) processing, modification and folding, and assembly of ribosomal proteins. The formation and maturation of the earliest pre-60S particles requires structural remodeling by the Npa1 complex, but i...

ProteomicsIdentification of 60S pre-rRNA binding sites of human GNL3L GTPase
We reveal that the GNL3 paralogue GTPase, GNL3L, associates with pre-ribosomes. We map RNA contact sites on GNL3L as well as GNL3L binding sites on pre-rRNAs. Lack of GNL3L impairs synthesis of the 60S rRNAs and expression of GTPase inactive GNL3L causes defects in early steps of pre-rRNA processing...

ProteomicsNuclear VCP-like 2 (NVL2)-associated complex
LC-MSMS analysis of NVL2-associated pre-60S complex. To obtain more insights into the molecular mechanism of this effects caused by the mutant NVL2 in pre-60S complexes,we searched for additional proteins that preferentially interact with the NVL2(E365Q/E682Q) in comparison with wild-type NVL2. Co-m...

TranscriptomicsCircular non-coding RNA ANRIL modulates ribosomal RNA maturation and atherosclerosis in humans.
Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their role in human health and disease remains obscure. Here, we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of atherosclerotic cardiovascular disease on chromosome ...

ProteomicsThe integrated stress response regulates 18S nonfunctional rRNA decay in mammals
Abstract - 18S nonfunctional rRNA decay (NRD) detects and eliminates translationally nonfunctional 18S rRNA. While this process is critical for ribosome quality control, the mechanisms underlying nonfunctional 18S rRNA turnover remain elusive, particularly in mammals. Here, we show that mammalian 18...

ProteomicsEffect of Nop53 depletion on the compositional changes during pre-60S maturation
The eukaryotic ribosome biogenesis is a highly orchestrated multistep process that starts at the nucleolus with the transcription of pre-rRNAs 5S and 35S. The latter comprises the mature 18S, 5.8S and 25S rRNAs separated by internal transcribed spacers (ITS1 and ITS2) and externally flanked by the 5...

OtherHigh-throughput RNA structure probing reveals critical folding events during early 60S ribosome assembly in yeast.
While the protein composition of various yeast 60S ribosomal subunit assembly intermediates has been studied in detail, little is known about ribosomal RNA (rRNA) structural rearrangements that take place during early 60S assembly steps. Using a high-throughput RNA structure probing method, we provi...
