Investigation of IRES Insertion into the Genome of Recombinant MVA as a Translation Enhancer in the Context of Transcript Decapping. [PDF]
Recombinant modified vaccinia virus Ankara (MVA) has been used to deliver vaccine candidate antigens against infectious diseases and cancer. MVA is a potent viral vector for inducing high magnitudes of antigen-specific CD8+ T cells; however the cellular ...

Non-redundant roles for the human mRNA decapping cofactor paralogs DCP1a and DCP1b
The study represents the first functional dissection of the two human cofactors present in the RNA decapping complex, and, significantly, it evaluates their role in the transcript buffering system.

The DEAD box helicase, Dhh1p, functions in mRNA decapping and interacts with both the decapping and deadenylase complexes [PDF]
A major pathway of mRNA turnover in eukaryotic cells initiates with deadenylation, leading to mRNA decapping and subsequent 5' to 3' exonuclease digestion. We show that a highly conserved member of the DEAD box family of helicases, Dhh1p, stimulates mRNA decapping in yeast. In dhh1delta mutants, mRNAs accumulate as deadenylated, capped species. Dhh1p's

mRNA Decapping Factors LSM1 and PAT Paralogs Are Involved in Turnip Mosaic Virus Viral Infection
Turnip mosaic virus is a devastating potyvirus infecting many economically important brassica crops. In response to this, the plant host engages its RNA silencing machinery, involving AGO proteins, as a prominent strategy to restrain turnip mosaic virus (

Targeted mRNA Degradation by Deadenylation-Independent Decapping [PDF]
Modulating the rate of mRNA degradation is a fast and efficient way to control gene expression. In a yeast strain deleted of EDC3, a component of the decapping machinery conserved in eukaryotes, the transcript coding the ribosomal protein Rps28b is specifically stabilized, as demonstrated by microarray and time course experiments.

Small RNA pathways in mammalian oocytes
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

The eIF4E-binding protein Eap1p functions in Vts1p-mediated transcript decay. [PDF]
Sequence-specific RNA binding proteins can induce the degradation of mRNAs through their ability to recruit proteins that trigger transcript destabilization. For example, Vts1p, the S.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

HPat a decapping activator interacting with the miRNA effector complex.
Animal miRNAs commonly mediate mRNA degradation and/or translational repression by binding to their target mRNAs. Key factors for miRNA-mediated mRNA degradation are the components of the miRNA effector complex (AGO1 and GW182) and the general mRNA ...

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.
