Developmental Effects of Decapping
Science, 2007STKE The balance between synthesis and degradation controls mRNA abundance. Goeres et al. have found that the 5′ to 3′ mRNA degradation pathway involves an mRNA decapping complex and is crucial for seedling development in Arabidopsis . The phenotypes of varicose ( vcs ) and trident ( tdt ) mutants were similar: defective leaf formation with vein ...

Normal and Aberrantly Capped mRNA Decapping
2012Messenger RNAs transcribed by RNA polymerase II are modified at their 5'-end by the cotranscriptional addition of a 7-methylguanosine (m(7)G) cap. The cap is an important modulator of gene expression and the mechanism and components involved in its removal have been extensively studied.

Abstract Removing the root cap of Zea mays prevents geoperception. But georeactivity may be regained after several hours. The time necessary to recover geosensitivity (GRT) is calculated using an intercept method. GRT is less for the short roots than for longer ones.

mRNA decapping activities and their biological roles
Biochimie, 1996The 5' cap structure of eukaryotic mRNAs is significant for a variety of cellular events and also serves to protect mRNAs from premature degradation. Analysis of mRNA decay in Saccharomyces cerevisiae has shown that removal of the 5' cap structure is a key step in the turnover of many yeast mRNAs, and that this decapping is carried out by Dcp1p.

Methods in enzymology, 2009
The modulation of mRNA decay is a critical determinant in the regulation of gene expression. mRNAs in eukaryotes are primarily degraded by two major exonucleolytic pathways: the 5' to 3'-and the 3' to 5'-pathways, both of which are initiated by removal of the polyadenylated (poly(A)) tail.

New insights into the control of mRNA decapping
Trends in Biochemical Sciences, 2006mRNA decapping irreversibly targets mRNAs for fast decay. Cap removal is catalyzed by decapping protein Dcp2 but also requires Dcp1. Recently, two groups have provided a first glimpse of the regulation mechanism of this crucial step in gene expression. Resolution of the yeast Dcp2 structure has enabled identification of the residues that are important ...

Assessing Messenger RNA Decapping in Cellular Extracts
2004Removal of the 5' cap from a messenger RNA (mRNA) is an integral part of all mRNA decay pathways and can be a highly regulated event. Assays designed to assess decapping in vitro need to effectively resolve four products of mRNA decay: 7meGpppG produced by 3'-5' shortening of the transcript by the exosome, 7meGMP produced by the scavenger decapping ...

Leakage Optimized DECAP Design for FPGAs
APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006On-chip decoupling capacitors (Decaps) are widely used to mitigate on-chip power supply noise. At and below 100nm on-chip decaps face leakage and area overhead problems associated with it and is estimated to increase with technology scaling. A recent work has proposed a gated decap structure to reduce leakage in decaps.

Rapid Brood Decapping for Tropilaelaps mercedesae Detection
Bee WorldRecent reports show that Tropilaelaps mercedesae is spreading westward from Central Asia, representing a growing threat that could significantly alter the global apicultural landscape. Now more than ever, beekeepers and bee experts need effective field methods for detecting T. mercedesae mites in Apis mellifera colonies.
