Interactions between Upf1 and the decapping factors Edc3 and Pat1 in Saccharomyces cerevisiae. [PDF]

open access: yesPLoS ONE, 2011
In Saccharomyces cerevisiae, mRNA transcripts with premature termination codons are targeted for deadenylation independent decapping and 5' to 3' decay in a quality control pathway termed nonsense-mediated decay (NMD).

Dcp2 C-terminal -binding elements control selective targeting of the decapping enzyme by forming distinct decapping complexes

open access: yes, 2022
A single Dcp1-Dcp2 decapping enzyme targets diverse classes of yeast mRNAs for decapping-dependent 5' to 3' decay, but the molecular mechanisms controlling mRNA selectivity by the enzyme remain elusive.

A Novel NAD-RNA Decapping Pathway Discovered by Synthetic Light-Up NAD-RNAs

open access: yesBiomolecules, 2020
The complexity of the transcriptome is governed by the intricate interplay of transcription, RNA processing, translocation, and decay. In eukaryotes, the removal of the 5’-RNA cap is essential for the initiation of RNA degradation.

The Mimivirus L375 Nudix enzyme hydrolyzes the 5' mRNA cap.

open access: yesPLoS ONE, 2021
The giant Mimivirus is a member of the nucleocytoplasmic large DNA viruses (NCLDV), a group of diverse viruses that contain double-stranded DNA (dsDNA) genomes that replicate primarily in eukaryotic hosts.

Degradation of YRA1 Pre-mRNA in the cytoplasm requires translational repression, multiple modular intronic elements, Edc3p, and Mex67p. [PDF]

open access: yesPLoS Biology, 2010
Intron-containing pre-mRNAs are normally retained and processed in the nucleus but are sometimes exported to the cytoplasm and degraded by the nonsense-mediated mRNA decay (NMD) pathway as a consequence of their inclusion of intronic in-frame termination

DDX20: A Multifunctional Complex Protein

open access: yesMolecules, 2023
DEAD-box decapping enzyme 20 (DDX20) is a putative RNA-decapping enzyme that can be identified by the conserved motif Asp–Glu–Ala–Asp (DEAD). Cellular processes involve numerous RNA secondary structure alterations, including translation initiation ...

Structure of the activated Edc1-Dcp1-Dcp2-Edc3 mRNA decapping complex with substrate analog poised for catalysis

open access: yesNature Communications, 2018
The decapping enzyme Dcp2 removes the 5′ eukaryotic cap from mRNA transcripts and acts in concert with its essential activator Dcp1 and various coactivators.

Characterization of the African Swine Fever Virus Decapping Enzyme during Infection. [PDF]

open access: yesJ Virol, 2017
African swine fever virus (ASFV) infection is characterized by a progressive decrease in cellular protein synthesis with a concomitant increase in viral protein synthesis, though the mechanism by which the virus achieves this is still unknown.

Eukaryotic mRNA decapping factors: molecular mechanisms and activity

open access: yes, 2022
Decapping is the enzymatic removal of 5' cap structures from mRNAs in eukaryotic cells. Cap structures normally enhance mRNA translation and stability, and their excision commits an mRNA to complete 5'-3' exoribonucleolytic digestion and generally ends ...

Regulation of gene expression in trypanosomatids: living with polycistronic transcription [PDF]

open access: yesOpen Biology, 2019
In trypanosomes, RNA polymerase II transcription is polycistronic and individual mRNAs are excised by trans-splicing and polyadenylation. The lack of individual gene transcription control is compensated by control of mRNA processing, translation and ...
