    Functioni

    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 By similarity.By similarity

    Catalytic activityi

    Miscellaneousi

    Miscellaneous

    South Carolina isolate has been sequenced from formalid fixed-lung tissues of a 21-year-old male which died in 1918 at Ft. Jackson, SC. Brevig Mission isolate has been sequenced from lung tissues of an Inuit woman buried in the permafrost in a gravesite near Brevig Mission, Alaska. This sample was recovered by John Hultin, retired pathologist.
