CC -!- FUNCTION: RNA-dependent RNA polymerase, which is responsible for the CC replication and transcription of the viral RNA genome using antigenomic CC RNA as an intermediate. During transcription, synthesizes subgenomic CC RNAs and assures their capping by a cap-snatching mechanism, which CC involves the endonuclease activity cleaving the host capped pre-mRNAs. CC These short capped RNAs are then used as primers for viral CC transcription. The 3'-end of subgenomic mRNAs molecules are CC heterogeneous and not polyadenylated. The replicase function is to CC direct synthesis of antigenomic and genomic RNA which are encapsidated CC and non capped. As a consequence of the use of the same enzyme for both CC transcription and replication, these mechanisms need to be well CC coordinated. These processes may be regulated by proteins N and Z in a CC dose-dependent manner. {ECO:0000256|PIRNR:PIRNR000836}.
