Modeling RNA degradation for RNA-Seq with applications [PDF]

open access: yesBiostatistics, 2012
RNA-Seq is widely used in biological and biomedical studies. Methods for the estimation of the transcript's abundance using RNA-Seq data have been intensively studied, many of which are based on the assumption that the short-reads of RNA-Seq are uniformly distributed along the transcripts.

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.

RNA Unwinding by the Trf4/Air2/Mtr4 Polyadenylation (TRAMP) Complex [PDF]

open access: yes, 2012
Many RNA-processing events in the cell nucleus involve the Trf4/Air2/Mtr4 polyadenylation (TRAMP) complex, which contains the poly(A) polymerase Trf4p, the Zn-knuckle protein Air2p, and the RNA helicase Mtr4p.

RNA quality control: degradation of defective transfer RNA [PDF]

open access: yesThe EMBO Journal, 2002
The distinction between stable (tRNA and rRNA) and unstable (mRNA) RNA has been considered an important feature of bacterial RNA metabolism. One factor thought to contribute to the difference between these RNA populations is polyadenylation, which promotes degradation of unstable RNA.

The 5' → 3' exoribonuclease XRN1/Pacman and its functions in cellular processes and development [PDF]

open access: yes, 2012
XRN1 is a 5' → 3' processive exoribonuclease that degrades mRNAs after they have been decapped. It is highly conserved in all eukaryotes, including homologs in Drosophila melanogaster (Pacman), Caenorhabditis elegans (XRN1), and Saccharomyces cerevisiae (

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]

open access: yes, 2019
Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability [PDF]

open access: yes, 2018
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent R loops may become pathological

Dengue Virus Genome Uncoating Requires Ubiquitination [PDF]

open access: yes, 2016
The process of genome release or uncoating after viral entry is one of the least-studied steps in the flavivirus life cycle. Flaviviruses are mainly arthropod-borne viruses, including emerging and reemerging pathogens such as dengue, Zika, and West Nile ...

Suppressing nonsense--a surprising function for 5-azacytidine. [PDF]

open access: yes, 2014
In this issue of EMBO Molecular Medicine, Bhuvanagiri et al report on a chemical means to convert molecular junk into gold. They identify a chemical inhibitor of a quality control pathway that is best known for its ability to clear cells of rubbish, but ...
