Export of piRNA precursors by EJC triggers assembly of cytoplasmic Yb-body in Drosophila

Nature Communications, 2016
In Drosophila ovarian follicle cells, piRNAs generated from RNA precursors are processed in cytoplasmic Yb-bodies. The authors identify the exportin and the exon junction complexes as required to transfer precursors to cytoplasm.

Understanding the Effects of Trenbolone Acetate, Polyamine Precursors, and Polyamines on Proliferation, Protein Synthesis Rates, and the Abundance of Genes Involved in Myoblast Growth, Polyamine Biosynthesis, and Protein Synthesis in Murine Myoblasts

Biology, 2023
Research suggests that androgens increase skeletal muscle growth by modulating polyamine biosynthesis. As such, the objective of this study was to investigate effects of anabolic hormones, polyamine precursors, and polyamines relative to proliferation ...

Pseudouridylation of yeast ribosomal precursor RNA

Nucleic Acids Research, 1979
The pseudouridylation of ribosomal RNA of Saccharomyces carlsbergensis was investigated with respect to its timing during the maturation of rRNA and its sequence specificity. Analysis of 37-S RNA, the common precursor to 17-S, 5.8-S and 26-S rRNA and most probably the primary ribosomal transcript, shows that this RNA molecule contains already most if ...

Attachment of the RNA degradosome to the bacterial inner cytoplasmic membrane prevents wasteful degradation of rRNA in ribosome assembly intermediates.

PLoS Biology, 2023
RNA processing and degradation shape the transcriptome by generating stable molecules that are necessary for translation (rRNA and tRNA) and by facilitating the turnover of mRNA, which is necessary for the posttranscriptional control of gene expression ...

Ancient and novel small RNA pathways compensate for the loss of piRNAs in multiple independent nematode lineages [PDF]

, 2015
Date of Acceptance: 02/01/2015Small RNA pathways act at the front line of defence against transposable elements across the Eukaryota. In animals, Piwi interacting small RNAs (piRNAs) are a crucial arm of this defence.

Structural basis of RNA polymerase I pre-initiation complex formation and promoter melting

Nature Communications, 2020
RNA polymerase I (Pol I) catalyses the transcription of ribosomal RNA precursors, and its transcription initiation mechanism differs from that of Pol II and Pol III.

Stability and Precursor Relationships of Virus RNA

Journal of General Virology, 1972
Summary Pulse-chase experiments with [3H]-uridine were performed with glucosamine-treated chick cells infected by RNA viruses. It was established that in cells infected by fowl plague virus both virus RNA and the RNA with the complementary base sequence were metabolically stable.

Functional characterization of Ysh1p, the yeast endonuclease involved in 3" end processing and in transcription termination of RNA polymerase II transcripts [PDF]

, 2008
Eukaryotic RNA polymerase II (RNAP II) is involved in the synthesis of two major classes of transcripts: messenger RNAs (mRNAs) and small nuclear and small nucleolar RNAs.

Rrp47p is an exosome-associated protein required for the 3 ' processing of stable RNAs [PDF]

, 2003
Related exosome complexes of 3'-->5' exonucleases are present in the nucleus and the cytoplasm. Purification of exosome complexes from whole-cell lysates identified a Mg2+-labile factor present in substoichiometric amounts. This protein was identified
