CC -!- FUNCTION: RNA-dependent RNA polymerase which is responsible for
CC replication and transcription of virus RNA segments. The transcription
CC of viral mRNAs occurs by a unique mechanism called cap-snatching. 5'
CC methylated caps of cellular mRNAs are cleaved after 10-13 nucleotides
CC by PA. In turn, these short capped RNAs are used as primers by PB1 for
CC transcription of viral mRNAs. During virus replication, PB1 initiates
CC RNA synthesis and copy vRNA into complementary RNA (cRNA) which in turn
CC serves as a template for the production of more vRNAs.
