Cis-acting RNA elements at the 5' end of Sindbis virus genome RNA regulate minus- and plus-strand RNA synthesis.

Alphavirus genome replication is a multistep asymmetric process. Several lines of evidence suggest that the template preference of the RNA replicase is regulated by proteolytic cleavage of the viral nonstructural polyprotein. Cis-acting RNA elements in the viral genome also play crucial roles in regulating genome replication and subgenomic RNA transcription. In this report, a series of RNA temp...

The Functional Roles of the Cis-acting Elements in Bamboo mosaic virus RNA Genome

Bamboo mosaic virus (BaMV), which belongs to the genus Potexvirus in the family Alphaflexiviridae, has a single-stranded positive-sense RNA genome that is approximately 6400 nucleotides (nts) in length. Positive-sense RNA viruses can use genomic RNA as a template for translation and replication after entering a suitable host cell. Furthermore, such viral RNA is recognized by capsid protein for ...

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...

cis-acting elements in the lytic origin of DNA replication of Epstein-Barr virus.

oriLyt, the cis-acting element of Epstein-Barr virus, mediates viral DNA replication in the lytic phase of the virus's life cycle. Oligonucleotide-directed in vitro mutagenesis of oriLyt plasmids allowed the identification of two noncontiguous components within the complex structure of oriLyt. Both components were indispensable for DNA replication of this origin. The upstream component colocali...

Mutagenic analysis of the 3' cis-acting elements of the rubella virus genome.

Thermodynamically predicted secondary structure analysis of the 3'-terminal 305 nucleotides (nt) of the rubella virus (RUB) genome, a region conserved in all RUB defective interfering RNAs, revealed four stem-loop (SL) structures; SL1 and SL2 are both located in the E1 coding region, while SL3 and SL4 are within the 59-nt 3' untranslated region (UTR) preceding the poly(A) tract. SL2 is a struct...
