Eukaryotic 5' mRNA cap structures participate to the post-transcriptional control of gene expression before being released by the two main mRNA decay pathways. In the 3'-5' pathway, the exosome generates free cap dinucleotides (m7GpppN) or capped oligoribonucleotides that are hydrolyzed

Myosins are actin-based molecular motors which are enzymatically adapted for their cellular functions such as transportation and membrane tethering. Human Myo19 affects mitochondrial motility, and promotes their localization to stress-induced filopodia. Therefore, studying Myo19 enzymology is essential to understand how

Eukaryotic cells utilize DcpS, a scavenger decapping enzyme, to degrade the residual cap structure following 3'-5' mRNA decay, thereby preventing the premature decapping of the capped long mRNA and misincorporation of methylated nucleotides in nucleic acids. We report the structures

The Arabidopsis thaliana decapping enzyme (AtDcp2) was characterized by bioinformatics analysis and by biochemical studies of the enzyme and mutants produced by recombinant expression. Three functionally significant regions were detected: (i) a highly disordered C-terminal region with a putative PSD-95

A method for extracting kinetic and optical parameters from progress curves for protein-ligand association, obtained by stopped-flow experiments, is described. The method is limited to one-step and two-step association kinetics, but it allows concentration of protein and offset of the

The reactions of a 5'-cap model compound P1-(7-methylguanosine) P3-guanosine 5',5'-triphosphate, m7GpppG, were studied in the presence of three different macrocyclic amines (2-4) under neutral conditions. The only products observed in the absence of the macrocycles resulted from the base-catalysed imidazole

Leishmania and other trypanosomatids are early eukaryotes that possess unusual molecular features, including polycistronic transcription and trans-splicing of pre-mRNAs. The spliced leader RNA (SL RNA) is joined to the 5' end of all mRNAs, thus donating a 5' cap that

While decapping plays a major role in mRNA turnover in yeast, biochemical evidence for a similar activity in mammalian cells has been elusive. We have now identified a decapping activity in HeLa cytoplasmic extracts that releases (7me)GDP from capped transcripts.

The eukaryotic translation initiation factor eIF4E acts in the nuclear export and translation of a subset of mRNAs. Both of these functions contribute to its oncogenic potential. While the biochemical mechanisms that underlie translation are relatively well understood, the molecular

Eukaryotic mRNA degradation proceeds through two main pathways, both involving mRNA cap breakdown. In the 3'-5' mRNA decay pathway, mRNA body degradation generates free m7GpppN that is hydrolyzed by DcpS generating m7GMP. In the 5'-3' pathway, the recently identified human

Site-specific recognition of DNA modification or the formation of noncanonical structures has important applications in molecular biology, disease diagnosis, and gene expression analysis. In this study, we introduce a guanine-guided sensing tool using a terbium(III)-platinum(II) complex (TPC) as a time-resolved

We report an industrial scale facile synthesis of 7-methyl guanosine 5'-diphosphate, which plays an important role in synthesis of various mRNA cap analogs. An efficient and selective methylation at position 7 of guanosine 5'-diphosphate was achieved by dissolving guanosine 5'-diphosphate
7-methylguanosine diphosphate (m7GDP) is not hydrolyzed but strongly bound by Decapping Scavenger (DcpS) enzymes and potently inhibits their activity

The eukaryotic cap and poly(A) tail binding proteins, eIF4E and Pab1p, play important roles in the initiation of protein synthesis. The recent structures of the complex of eIF4E bound to the methylated guanosine (cap) found at the 5'end of messenger

eIF4E, the mRNA cap binding protein, is a master switch that controls eukaryotic translation. To be active, it must bind eIF4G and form the eIF4F complex, which also contains eIF4A. Translation is downregulated by association of eIF4E with 4E-BP, which

Vaccinia virus (VACV) encodes enzymes that cap the 5' end of viral mRNAs, which enhances their stability and translation. Nevertheless, recent studies demonstrated that the VACV D10 protein (VACV-WR_115) decaps mRNA, an enzymatic activity not previously shown to be encoded

eIF4G uses a conserved Tyr-X-X-X-X-Leu-phi segment (where X is variable and phi is hydrophobic) to recognize eIF4E during cap-dependent translation initiation in eukaryotes. High-resolution X-ray crystallography and complementary biophysical methods have revealed that this eIF4E recognition motif undergoes a disorder-to-order

Decapping scavenger (DcpS) enzymes catalyze the cleavage of a residual cap structure following 3' → 5' mRNA decay. Some previous studies suggested that both m(7)GpppG and m(7)GDP were substrates for DcpS hydrolysis. Herein, we show that mononucleoside diphosphates, m(7)GDP (7-methylguanosine
