Eukaryotic mRNA Decapping Activation
The 5′-terminal cap is a fundamental determinant of eukaryotic gene expression which facilitates cap-dependent translation and protects mRNAs from exonucleolytic degradation.

Multiple mRNA Decapping Enzymes in Mammalian Cells [PDF]
Regulation of RNA degradation plays an important role in the control of gene expression. One mechanism of eukaryotic mRNA decay proceeds through an initial deadenylation followed by 5' end decapping and exonucleolytic decay. Dcp2 is currently believed to be the only cytoplasmic decapping enzyme responsible for decapping of all mRNAs.

General Translational Repression by Activators of mRNA Decapping [PDF]
Translation and mRNA degradation are affected by a key transition where eukaryotic mRNAs exit translation and assemble an mRNP state that accumulates into processing bodies (P bodies), cytoplasmic sites of mRNA degradation containing non-translating mRNAs, and mRNA degradation machinery.

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.

Removal of the 5′ cap structure of RNAs (termed decapping) is a pivotal event in the life of cytoplasmic mRNAs mainly catalyzed by a conserved holoenzyme, composed of the catalytic subunit DCP2 and its essential cofactor DCP1.

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).

Degradation of most yeast mRNAs involves decapping by Dcp1/Dcp2. DEAD-box protein Dhh1 has been implicated as an activator of decapping, in coupling codon non-optimality to enhanced degradation, and as a translational repressor, but its functions in ...

The DEAD-box protein Dhh1 promotes decapping by slowing ribosome movement. [PDF]
Translational control and messenger RNA (mRNA) decay represent important control points in the regulation of gene expression. In yeast, the major pathway for mRNA decay is initiated by deadenylation followed by decapping and 5'-3' exonucleolytic ...

Targeting mRNA Decapping in AML [PDF]
In this issue of Cancer Cell, Yamauchi et al. identify a dependency of acute myeloid leukemia (AML) on DCPS, which catalyzes the final step of 3'-to-5' mRNA decay and is implicated in numerous aspects of RNA metabolism. DCPS is targetable with a clinical inhibitor, underscoring the translational importance of this discovery.

Transcript-Specific Decapping and Regulated Stability by the Human Dcp2 Decapping Protein [PDF]
mRNA decapping is a critical step in the control of mRNA stability and gene expression and is carried out by the Dcp2 decapping enzyme. Dcp2 is an RNA binding protein that must bind RNA in order to recognize the cap for hydrolysis. We demonstrate that human Dcp2 (hDcp2) preferentially binds to a subset of mRNAs and identify sequences at the 5' terminus
