General decapping activators target different subsets of inefficiently translated mRNAs
The Dcp1-Dcp2 decapping enzyme and the decapping activators Pat1, Dhh1, and Lsm1 regulate mRNA decapping, but their mechanistic integration is unknown. We analyzed the gene expression consequences of deleting PAT1, LSM1, or DHH1, or the DCP2 C-terminal ...

Poxvirus-encoded decapping enzymes promote selective translation of viral mRNAs.
Cellular decapping enzymes negatively regulate gene expression by removing the methylguanosine cap at the 5' end of eukaryotic mRNA, rendering mRNA susceptible to degradation and repressing mRNA translation. Vaccinia virus (VACV), the prototype poxvirus,

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

Is mRNA decapping by ApaH like phosphatases present in eukaryotes beyond the Kinetoplastida?
Background ApaH like phosphatases (ALPHs) originate from the bacterial ApaH protein and have been identified in all eukaryotic super-groups. Only two of these proteins have been functionally characterised.

Decapping enzymes remove the 5′ cap of eukaryotic mRNA, leading to accelerated RNA decay. They are critical in regulating RNA homeostasis and play essential roles in many cellular and life processes.

The ApaH-like phosphatase TbALPH1 is the major mRNA decapping enzyme of trypanosomes. [PDF]
5'-3' decay is the major mRNA decay pathway in many eukaryotes, including trypanosomes. After deadenylation, mRNAs are decapped by the nudix hydrolase DCP2 of the decapping complex and finally degraded by the 5'-3' exoribonuclease. Uniquely, trypanosomes

Protected long-time storage of a topological insulator
The physical investigation of surfaces and their properties crucially depends on their quality. Such investigations are commonly performed in an ultra-high vacuum environment.

The mRNA decapping machinery targets LBD3/ASL9 to mediate apical hook and lateral root development
This study identifies LBD3/ASL9 as targets of mRNA decay machinery, and ASL9 contributes to apical hook and lateral root development, possibly through interfering with cytokinin/auxin responses.

How Cancer Exploits Ribosomal RNA Biogenesis: A Journey beyond the Boundaries of rRNA Transcription
The generation of new ribosomes is a coordinated process essential to sustain cell growth. As such, it is tightly regulated according to cell needs. As cancer cells require intense protein translation to ensure their enhanced growth rate, they exploit ...

Attacked from All Sides: RNA Decay in Antiviral Defense
The innate immune system has evolved a number of sensors that recognize viral RNA (vRNA) to restrict infection, yet the full spectrum of host-encoded RNA binding proteins that target these foreign RNAs is still unknown.
