Conserved Stem II of the Box C/D Motif Is Essential for Nucleolar Localization and Is Required, Along with the 15.5K Protein, for the Hierarchical Assembly of the Box C/D snoRNP: Molecular and Cellular Biology: Vol 22, No 23
The 5′ stem-loop of the U4 snRNA and the box C/D motif of the box C/D snoRNAs can both be folded into a similar stem-internal loop-stem structure that binds the 15.5K protein. The homologous proteins NOP56 and NOP58 and 61K (hPrp31) associate with the box C/D snoRNPs and the U4/U6…
Rok1p Is a Putative RNA Helicase Required for rRNA Processing: Molecular and Cellular Biology: Vol 17, No 6
The synthesis of ribosomes involves many small nucleolar ribonucleoprotein particles (snoRNPs) as trans-acting factors. Yeast strains lacking the snoRNA, snR10, are viable but are impaired in growth and delayed in the early pre-rRNA cleavages at sites A0, A1, and A2, which lead to the synthesis of 18S rRNA. The same…
Coupling between snoRNP assembly and 3′ processing controls box C/D snoRNA biosynthesis in yeast
journal contribution posted on 2004-06-16, 00:00 authored by M Morlando, M Ballarino, P Greco, E Caffarelli, Bernhard DichtlBernhard Dichtl, I Bozzoni RNA polymerase II transcribes genes encoding proteins and a large number of small stable RNAs. While pre-mRNA 3′-end formation requires a machinery ensuring tight coupling between cleavage and polyadenylation,…

Abstract: Background Box C/D snoRNPs are responsible for rRNA methylation and processing, and are formed by snoRNAs and four conserved proteins, Nop1, Nop56, Nop58 and Snu13. The snoRNP assembly is a stepwise process, involving other protein complexes, among which the R2TP and Hsp90 chaperone. Nop17, also known as Pih1, has…
Mapping of the Chemical Modifications of rRNAs
Chemical modification of biomolecules is an impressive way of nature to expand their functional diversity. Like DNA and proteins, RNA molecules also undergo a variety of chemical modifications that allow them to enrich their topological potential and perform a variety of functions that go beyond their capacity to encode proteins…
