26584588 Data show that decapping scavenger enzyme DcpS (DcpS) is a nucleocytoplasmic shuttling protein that activates microRNA (miRNA) degradation.
26241964 In DcpS, conformational change is dominated by an anti-symmetric cooperative motion, causing one active site to close as the other opens; however a symmetric motion is also significant.
26001796 data demonstrate that DcpS in conjunction with Xrn1 has the potential to regulate RNA stability in a transcript-selective manner in mammalian cells
25712129 DCPS and more generally RNA catabolism, are critical for neurological development, normal cognition and organismal homeostasis in humans.
25701870 In vitro decapping assays showed that altered EDC3 is unable to enhance DCP2 decapping at low concentrations and even inhibits DCP2 decapping at high concentration.
18725266 Data established that DcpS, a key enzyme in mRNA decay, is a new target of DeltaLf transcriptional activity.
18441014 biochemical analysis of the dynamic and mutually exclusive cap hydrolysis activity of the two cap binding sites of DcpS
18426921 These studies demonstrate that the significance of DcpS extends beyond its well-characterized role in mRNA decay and involves a broader range of functions in RNA processing including nuclear pre-mRNA splicing.
16140270 Furthermore, we show that a novel human histidine triad protein DCS-1, which is expressed together with NR1 in many tissues, can significantly reduce menadione-induced cytotoxicity in these cells
15769464 crystal structures of DcpS in ligand-free form and in a complex with m7GDP
15068804 Structural and biochemical analysis suggests an autoregulatory mechanism whereby premature decapping mRNA is prevented by blocking the conformational changes that are required to form a closed productive active site capable of cap hydrolysis.
14523240 m7GDP breakdown by DcpS should prevent misincorporation of methylated nucleotides in nucleic acids and could generate a unique indicator allowing the cell to monitor mRNA decay.
12198172 The central histidine within the DcpS HIT motif is critical for decapping activity and defines the HIT motif as a new mRNA decapping domain, making DcpS the first member of the HIT family of proteins with a defined biological function.
