RNAi and double-strand RNA.
Double-strand RNA (dsRNA) is a signal for gene-specific silencing of expression in a number of organisms. This phenomenon was demonstrated recently in Caenorhabditis elegans when dsRNA was injected into the worm and the corresponding gene products disappeared from both the somatic cells of the organism as well as in its F1 progeny (Fire et al. 1998). This RNA interference, RNAi, has been genera...
متن کاملDynamic profiling of double-stranded RNA binding proteins
Double-stranded (ds) RNA is a key player in numerous biological activities in cells, including RNA interference, anti-viral immunity and mRNA transport. The class of proteins responsible for recognizing dsRNA is termed double-stranded RNA binding proteins (dsRBP). However, little is known about the molecular mechanisms underlying the interaction between dsRBPs and dsRNA. Here we examined four h...
متن کاملThe RNA binding protein Npl3 promotes resection of DNA double-strand breaks by regulating the levels of Exo1
Eukaryotic cells preserve genome integrity upon DNA damage by activating a signaling network that promotes DNA repair and controls cell cycle progression. One of the most severe DNA damage is the DNA double-strand break (DSB), whose 5΄ ends can be nucleolitically resected by multiple nucleases to create 3΄-ended single-stranded DNA tails that trigger DSB repair by homologous recombination. Here...
متن کاملPARP activation regulates the RNA-binding protein NONO in the DNA damage response to DNA double-strand breaks
After the generation of DNA double-strand breaks (DSBs), poly(ADP-ribose) polymerase-1 (PARP-1) is one of the first proteins to be recruited and activated through its binding to the free DNA ends. Upon activation, PARP-1 uses NAD+ to generate large amounts of poly(ADP-ribose) (PAR), which facilitates the recruitment of DNA repair factors. Here, we identify the RNA-binding protein NONO, a partne...
متن کاملA new double-stranded RNA binding protein (DRBP-120) is associated with double-stranded RNA-activated protein kinase (PKR).
Double-stranded RNA-activated protein kinase (PKR) plays an important role in interferon-induced antiviral responses, and is also involved in intracellular signaling pathways, including the apoptosis, proliferation, and transcription pathways. In this study, a new 120-kDa PKR-associated protein designated double-stranded RNA binding protein (DRBP)-120 was identified using co-immunoprecipitation...
