CC -!- FUNCTION: Plays an essential role in transcription initiation and CC cap-stealing mechanism, in which cellular capped pre-mRNAs are CC used to generate primers for viral transcription. CC {ECO:0000256|RuleBase:RU361246}. CC -!- SUBUNIT: Influenza RNA polymerase is composed of three subunits: CC PB1, PB2 and PA. {ECO:0000256|RuleBase:RU361246}. CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000256|RuleBase:RU361246}. Host CC nucleus {ECO:0000256|RuleBase:RU361246}. CC -!- SIMILARITY: Belongs to the influenza viruses PB2 family.
