cis- and trans-acting elements in flavivirus RNA replication.
Most of the seven flavivirus nonstructural proteins (NS1 to NS5) encoded in the distal two-thirds of the RNA positive-sense genome are believed to be essential components of RNA replication complexes. To explore the functional relationships of these components in RNA replication, we used trans-complementation analysis of full-length infectious RNAs of Kunjin (KUN) virus with a range of lethal i...
متن کاملSomatic Primary piRNA Biogenesis Driven by cis-Acting RNA Elements and trans-Acting Yb.
Primary piRNAs in Drosophila ovarian somatic cells arise from piRNA cluster transcripts and the 3' UTRs of a subset of mRNAs, including Traffic jam (Tj) mRNA. However, it is unclear how these RNAs are determined as primary piRNA sources. Here, we identify a cis-acting 100-nt fragment in the Tj 3' UTR that is sufficient for producing artificial piRNAs from unintegrated DNA. These artificial piRN...

متن کاملtrans-Acting factors and cis elements involved in glucose repression of arabinan degradation in Bacillus subtilis.
In Bacillus subtilis, the synthesis of enzymes involved in the degradation of arabinose-containing polysaccharides is subject to carbon catabolite repression (CCR). Here we show that CcpA is the major regulator of repression of the arabinases genes in the presence of glucose. CcpA acts via binding to one cre each in the promoter regions of the abnA and xsa genes and to two cres in the araABDLMN...
متن کاملVasopressin mRNA localization in nerve cells: characterization of cis-acting elements and trans-acting factors.
mRNA localization is a complex pathway. Besides mRNA sorting per se, this process includes aspects of regulated translation. It requires protein factors that interact with defined sequences (or sequence motifs) of the transcript, and the protein/RNA complexes are finally guided along the cytoskeleton to their ultimate destinations. The mRNA encoding the vasopressin (VP) precursor protein is loc...
