OX NCBI_TaxID=1293832 {ECO:0000313|EMBL:AGG53297.1}; RN [1] {ECO:0000313|EMBL:AGG53297.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=A/Northern shoveler/Korea/SD175/2008 RC {ECO:0000313|EMBL:AGG53297.1}; RA Kang H.-M., Park H.-Y., Lee K.-J., Choi J.-G., Lee E.-K., Song B.-M., RA Lee H.-S., Lee Y.-J.; RT "Ecology of H7 avian influenza viruses in wild birds in South Korea RT and their genetic comparison with novel H7N9 viruses circulating in RT China."; RL Submitted (FEB-2013) to the EMBL/GenBank/DDBJ databases. 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 -!- SUBCELLULAR LOCATION: Host nucleus CC {ECO:0000256|SAAS:SAAS00844384}. CC -!- SIMILARITY: Belongs to the influenza viruses PB2 family.
