Elucidating the role of H/ACA-like RNAs in trans-splicing and rRNA processing via RNA interference silencing of the Trypanosoma brucei CBF5 pseudouridine synthase.

The Journal of biological chemistry - 14 Oct 2005

Abstract excerpt

Most pseudouridinylation in eukaryotic rRNA and small nuclear RNAs is guided by H/ACA small nucleolar RNAs. In this study, the Trypanosoma brucei pseudouridine synthase, Cbf5p, a snoRNP protein, was identified and silenced by RNAi. Depletion of this protein destabilized all small nucleolar RNAs of the H/ACA-like family. Following silencing, defects in rRNA processing, such as accumulation of precursors and...
