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 (

Identification and functional analysis of novel phosphorylation sites in the RNA surveillance protein Upf1. [PDF]

open access: yes, 2013
One third of inherited genetic diseases are caused by mRNAs harboring premature termination codons as a result of nonsense mutations. These aberrant mRNAs are degraded by the Nonsense-Mediated mRNA Decay (NMD) pathway.

Structure of Csx1-cOA4 complex reveals the basis of RNA decay in Type III-B CRISPR-Cas

open access: yesNature Communications, 2019
Type III CRISPR-Cas multisubunit complexes cleave ssRNA and ssDNA. These activities promote the generation of cyclic oligoadenylate (cOA), which activates associated CRISPR-Cas RNases from the Csm/Csx families, triggering a massive RNA decay to provide ...

CCR4, a RNA decay factor, is hijacked by a plant cytorhabdovirus phosphoprotein to facilitate virus replication

open access: yeseLife, 2020
Carbon catabolite repression 4 (CCR4) is a conserved mRNA deadenylase regulating posttranscriptional gene expression. However, regulation of CCR4 in virus infections is less understood.

RNA decay and RNA silencing in plants: competition or collaboration?

open access: yesFrontiers in Plant Science, 2011
Initiation of RNA polymerase II transcription signals the beginning of a series of physically and functionally coupled pre-mRNA processing events that transform an RNA transcript into a highly structured, mature ribonucleoprotein complex.

Kaposi's sarcoma-associated herpesvirus ORF57 protein binds and protects a nuclear noncoding RNA from cellular RNA decay pathways. [PDF]

open access: yesPLoS Pathogens, 2010
The control of RNA stability is a key determinant in cellular gene expression. The stability of any transcript is modulated through the activity of cis- or trans-acting regulatory factors as well as cellular quality control systems that ensure the ...

4EHP and GIGYF1/2 Mediate Translation-Coupled Messenger RNA Decay.

open access: yesCell Reports, 2020
Current models of mRNA turnover indicate that cytoplasmic degradation is coupled with translation. However, our understanding of the molecular events that coordinate ribosome transit with the mRNA decay machinery is still limited. Here, we show that 4EHP-

A novel class of microRNA-recognition elements that function only within open reading frames. [PDF]

open access: yes, 2018
MicroRNAs (miRNAs) are well known to target 3' untranslated regions (3' UTRs) in mRNAs, thereby silencing gene expression at the post-transcriptional level.

RNA decay during gammaherpesvirus infection reduces RNA polymerase II occupancy of host promoters but spares viral promoters

open access: yesPLoS Pathogens, 2020
In mammalian cells, widespread acceleration of cytoplasmic mRNA degradation is linked to impaired RNA polymerase II (Pol II) transcription. This mRNA decay-induced transcriptional repression occurs during infection with gammaherpesviruses including ...

Characterizing ZC3H18, a Multi-domain Protein at the Interface of RNA Production and Destruction Decisions

open access: yesCell Reports, 2018
Summary: Nuclear RNA metabolism is influenced by protein complexes connecting to both RNA-productive and -destructive pathways. The ZC3H18 protein binds the cap-binding complex (CBC), universally present on capped RNAs, while also associating with the ...
