Paramyxovirus RNA synthesis, mRNA editing, and genome hexamer phase: A review

Abstract

The recent flurry of high resolution structures of Negative Strand RNA Virus RNA-dependent RNA polymerases has rekindled interest in the manner in which these polymerases, and in particular those of the nonsegmented viruses, recognize the RNA sequences that control mRNA synthesis and genome replication. In the light of these polymerase structures, we re-examine some unusual aspects of the Paramyxoviridae, namely bipartite replication promoters and mRNA editing, and the manner in which these properties are governed by genome hexamer phase.

Keywords: Bipartite replication promoters; Genome hexamer phase; MRNA editing; Paramyxoviridae family.
