Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
, 2010 For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

The 23S Ribosomal RNA From Pyrococcus furiosus Is Circularly Permuted
Frontiers in Microbiology, 2020 Synthesis and assembly of ribosomal components are fundamental cellular processes and generally well-conserved within the main groups of organisms. Yet, provocative variations to the general schemes exist. We have discovered an unusual processing pathway

Nop53p is required for late 60S ribosome subunit maturation and nuclear export in yeast [PDF]
, 2005 We report that Ypl146cp/Nop53p is associated with pre-60S ribosomal complexes and localized to the nucleolus and nucleoplasm. in cells depleted of Nop53p synthesis of the rRNA components of the 60S ribosomal subunit is severely inhibited, with strikingly

Autophagy regulates rRNA synthesis
Nucleus, 2022 Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

Roles of the HEAT repeat proteins Utp10 and Utp20 in 40S ribosome maturation [PDF]
, 2007 A family of HEAT-repeat containing ribosome synthesis factors was previously identified in Saccharomyces cerevisiae. We report the detailed characterization of two of these factors, Utp10 and Utp20, which were initially identified as components of the ...

Conformational switches control early maturation of the eukaryotic small ribosomal subunit
eLife, 2019 Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

RNA polymerase I transcription and pre-rRNA processing are linked by specific SSU processome components [PDF]
, 2004 Sequential events in macromolecular biosynthesis are often elegantly coordinated. The small ribosomal subunit (SSU) processome is a large ribonucleoprotein (RNP) required for processing of precursors to the small subunit RNA, the 18S, of the ribosome. We

Ribosomal RNA Transcription Regulation in Breast Cancer [PDF]
, 2021 Ribosome biogenesis is a complex process that is responsible for the formation of ribosomes and ultimately global protein synthesis. The first step in this process is the synthesis of the ribosomal RNA in the nucleolus, transcribed by RNA Polymerase I ...

Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]
, 2013 Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.
