Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]

open access: yes, 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.

Degradation of ribosomal RNA precursors by the exosome [PDF]

open access: yesNucleic Acids Research, 2000
The yeast exosome is a complex of 3'-->5' exonucleases involved in RNA processing and degradation. All 11 known components of the exosome are required during 3' end processing of the 5.8S rRNA. Here we report that depletion of each of the individual components inhibits the early pre-rRNA cleavages at sites A(0), A(1), A(2)and A(3), reducing the levels ...

Splicing of Messenger RNA Precursors

open access: yesScience, 1987
A general mechanism for the splicing of nuclear messenger RNA precursors in eukaryotic cells has been widely accepted. This mechanism, which generates lariat RNAs possessing a branch site, seems related to the RNA-catalyzed reactions of self-splicing introns.

From Formamide to RNA, the Path Is Tenuous but Continuous

open access: yesLife, 2015
Reactions of formamide (NH2COH) in the presence of catalysts of both terrestrial and meteoritic origin yield, in plausible and variegated conditions, a large panel of precursors of (pre)genetic and (pre)metabolic interest. Formamide chemistry potentially

The Drosophila ZAD zinc finger protein Kipferl guides Rhino to piRNA clusters

open access: yeseLife, 2022
RNA interference systems depend on the synthesis of small RNA precursors whose sequences define the target spectrum of these silencing pathways. The Drosophila Heterochromatin Protein 1 (HP1) variant Rhino permits transcription of PIWI-interacting RNA ...

Ribosomal Precursor RNA in Saccharomyces carlsbergensis [PDF]

open access: yesEuropean Journal of Biochemistry, 1967
Several lines of evidence for the occurrence of ribosomal precursor RNA in yeast are presented. This ribosomal precursor RNA has been found in the nuclear fraction, it is rapidly labeled with radioactive nucleotides and sediments faster than the two ribosomal RNAs.

Trim25 is an RNA-specific activator of Lin28a/TuT4-mediated uridylation [PDF]

open access: yes, 2014
RNA binding proteins have thousands of cellular RNA targets and often exhibit opposite or passive molecular functions. Lin28a is a conserved RNA binding protein involved in pluripotency and tumorigenesis that was previously shown to trigger TuT4-mediated

Complete probabilistic analysis of RNA shapes [PDF]

open access: yes, 2006
Voß B, Giegerich R, Rehmsmeier M. Complete probabilistic analysis of RNA shapes. BMC Biology. 2006;4(1): 5.Background: Soon after the first algorithms for RNA folding became available, it was recognised that the prediction of only one energetically ...

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]

open access: yes, 2012
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

Axon micro-dissection and transcriptome profiling reveals the in vivo RNA content of fully differentiated myelinated motor axons [PDF]

open access: yes, 2020
Axonal protein synthesis has been shown to play a role in developmental and regenerative growth, as well as in the maintenance of the axoplasm in steady state.
