Natl. Acad. Sci. U.S.A. 109:4269-4274(2012). CC -!- FUNCTION: Plays an essential role in transcription initiation and cap- CC stealing mechanism, in which cellular capped pre-mRNAs are used to CC generate primers for viral transcription. CC {ECO:0000256|RuleBase:RU361246}. CC -!- SUBUNIT: Influenza RNA polymerase is composed of three subunits: PB1, CC PB2 and PA. {ECO:0000256|RuleBase:RU361246}. CC -!- SUBCELLULAR LOCATION: Host mitochondrion CC {ECO:0000256|ARBA:ARBA00004181}. Mitochondrion CC {ECO:0000256|ARBA:ARBA00004173}. Virion CC {ECO:0000256|RuleBase:RU361246}. Host nucleus CC {ECO:0000256|RuleBase:RU361246}. CC -!- SIMILARITY: Belongs to the influenza viruses PB2 family. CC {ECO:0000256|ARBA:ARBA00008660, ECO:0000256|RuleBase:RU361246}.
