Nop9 binds the central pseudoknot region of 18S rRNA
The assembly of eukaryotic ribosomes requires numerous factors that transiently associate with evolving pre-ribosomal particles. The Pumilio repeat-containing protein Nop9 briefly associates with the 90S pre-ribosome during its co-transcriptional assembly. Here, we show that Nop9 specifically binds an 11-nucleotide sequence of 18S rRNA that forms the 3΄ side of the central pseudoknot and helix ...
متن کاملNop9 is a PUF-like protein that prevents premature cleavage to correctly process pre-18S rRNA
Numerous factors direct eukaryotic ribosome biogenesis, and defects in a single ribosome assembly factor may be lethal or produce tissue-specific human ribosomopathies. Pre-ribosomal RNAs (pre-rRNAs) must be processed stepwise and at the correct subcellular locations to produce the mature rRNAs. Nop9 is a conserved small ribosomal subunit biogenesis factor, essential in yeast. Here we report a ...
متن کاملfrom 18S rRNA Sequences
Several families in the beetle suborder Adephaga have an aquatic life style and are commonly grouped in the “Hydradephaga,” but their monophyly is contentious and relationships between and within these families are poorly understood. Here we present fulllength 18S rRNA sequence for 84 species of Hydradephaga, including representatives of most major groups down to the tribal level, and a total o...

15 صفحه اولNucleotide sequence of the region between the 18S rRNA sequence and the 28S rRNA sequence of rat ribosomal DNA.
The DNA sequence of the intragenic region of the rat 45S ribosomal RNA precursor was determined. This sequence contains 2282 nucleotides and extends from the conserved EcoR I site near the 3' terminus of 18S rRNA to 69 nucleotides downstream of the 5' terminus of 28S rRNA. The sequences corresponding to 18S and 5.8S rRNA were identified by comparison with previously published data. The 5' termi...
