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.

HIV mRNA Vaccines—Progress and Future Paths

open access: yesVaccines, 2021
The SARS-CoV-2 pandemic introduced the world to a new type of vaccine based on mRNA encapsulated in lipid nanoparticles (LNPs). Instead of delivering antigenic proteins directly, an mRNA-based vaccine relies on the host’s cells to manufacture protein ...

The Aberrant Expression of MicroRNA-125a-5p/IGF2BP3 Axis in Advanced Gastric Cancer and Its Clinical Relevance

open access: yesTechnology in Cancer Research & Treatment, 2020
RNA-binding proteins have been associated with cancer development. The overexpression of a well-known RNA-binding protein, insulin-like growth factor 2 messenger RNA–binding protein 3, has been identified as an indicator of poor prognosis in patients ...

RNA-specific ribonucleotidyl transferases [PDF]

open access: yes, 2007
RNA-specific nucleotidyl transferases (rNTrs) are a diverse family of template-independent polymerases that add ribonucleotides to the 3'-ends of RNA molecules.

Xp54 and related (DDX6-like) RNA helicases : roles in messenger RNP assembly, translation regulation and RNA degradation [PDF]

open access: yes, 2006
The DEAD-box RNA helicase Xp54 is an integral component of the messenger ribonucleoprotein (mRNP) particles of Xenopus oocytes. In oocytes, several abundant proteins bind pre-mRNA transcripts to modulate nuclear export, RNA stability and translational ...

An Endoribonuclease Functionally Linked to Perinuclear mRNP Quality Control Associates with the Nuclear Pore Complexes [PDF]

open access: yes, 2009
Nuclear mRNA export is a crucial step in eukaryotic gene expression, which is in yeast coupled to cotranscriptional messenger ribonucleoprotein particle ( mRNP) assembly and surveillance.

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

A new yeast poly(A) polymerase complex involved in RNA quality control [PDF]

open access: yes, 2005
Eukaryotic cells contain several unconventional poly(A) polymerases in addition to the canonical enzymes responsible for the synthesis of poly(A) tails of nuclear messenger RNA precursors.

Cytoplasmic RNA-dependent RNA-synthesis in maturing chicken erythrocytes. [PDF]

open access: yes, 1976
Includes bibliographical references.An RNA-dependent RNA polymerase from ribosomes of maturing chicken erythrocytes was investigated. Concurrent with an increase in globin and RNA synthesis during phenylhydrazine induced anaemia, the total and specific ...

Processivity and coupling in messenger RNA transcription.

open access: yesPLoS ONE, 2010
BackgroundThe complexity of messenger RNA processing is now being uncovered by experimental techniques that are capable of detecting individual copies of mRNA in cells, and by quantitative real-time observations that reveal the kinetics.
