== Function ==
 +
[https://www.uniprot.org/uniprot/RDRP_I34A1 RDRP_I34A1] RNA-dependent RNA polymerase which is responsible for replication and transcription of virus segments. Binds the promoter sequence of the encapsidated viral RNA. Displays an endonuclease activity involved in cap-stealing. Cleaves cellular pre-mRNA to generate primers for viral transcription.

== Publication Abstract from PubMed ==
 +
Influenza virus RNA-dependent RNA polymerase is a multi-functional heterotrimer, which uses a 'cap-snatching' mechanism to produce viral mRNA. Host cell mRNA is cleaved to yield a cap-bearing oligonucleotide, which can be extended using viral genomic RNA as a template. The cap-binding and endonuclease activities are only activated once viral genomic RNA is bound. This requires signalling from the RNA-binding PB1 subunit to the cap-binding PB2 subunit, and the interface between these two subunits is essential for the polymerase activity. We have defined this interaction surface by protein crystallography and tested the effects of mutating contact residues on the function of the holo-enzyme. This novel interface is surprisingly small, yet, it has a crucial function in regulating the 250 kDa polymerase complex and is completely conserved among avian and human influenza viruses.
