Human mitochondrial RNA decay mediated by PNPase–hSuv3 complex takes place in distinct foci
RNA decay is usually mediated by protein complexes and can occur in specific foci such as P-bodies in the cytoplasm of eukaryotes. In human mitochondria nothing is known about the spatial organization of the RNA decay machinery, and the ribonuclease responsible for RNA degradation has not been identified. We demonstrate that silencing of human polynucleotide phosphorylase (PNPase) causes accumu...
متن کاملNonsense-Mediated RNA Decay Influences Human Embryonic Stem Cell Fate
Nonsense-mediated RNA decay (NMD) is a highly conserved pathway that selectively degrades specific subsets of RNA transcripts. Here, we provide evidence that NMD regulates early human developmental cell fate. We found that NMD factors tend to be expressed at higher levels in human pluripotent cells than in differentiated cells, raising the possibility that NMD must be downregulated to permit di...
متن کاملFoci of decay
ytoplasmic structures are sites of active mammalian mRNA decay, according to Cougot et al. (page 31). The group had previously identified cytoplasmic foci that included two human mRNA decapping enzymes. They now add subunits of a deadenylase, exonuclease, and possible helicase to the list of proteins found at these sites. After inhibition of a 5 –3 exonuclease, poly(A) RNA accumulates at the sa...
متن کاملCytoplasmic foci are sites of mRNA decay in human cells
Understanding gene expression control requires defining the molecular and cellular basis of mRNA turnover. We have previously shown that the human decapping factors hDcp2 and hDcp1a are concentrated in specific cytoplasmic structures. Here, we show that hCcr4, hDcp1b, hLsm, and rck/p54 proteins related to 5'-3' mRNA decay also localize to these structures, whereas DcpS, which is involved in cap...
متن کاملThe nonsense-mediated decay RNA surveillance pathway.
Nonsense-mediated mRNA decay (NMD) is a quality-control mechanism that selectively degrades mRNAs harboring premature termination (nonsense) codons. If translated, these mRNAs can produce truncated proteins with dominant-negative or deleterious gain-of-function activities. In this review, we describe the molecular mechanism of NMD. We first cover conserved factors known to be involved in NMD in...
