Protein detail:
Protein name | Polymerase PB2 |
Uniprot protein ID | C3W5X5 |
Protein length | 759 amino acids |
Protein description | PB2 plays an essential role in transcription initiation and cap-stealing mechanism, in which cellular capped pre-mRNAs are used to generate primers for viral transcription. Recognizes and binds the 7-methylguanosine-containing cap of the target pre-RNA which is subsequently cleaved after 10-13 nucleotides by the viral protein PA. Plays a role in the initiation of the viral genome replication and modulates the activity of the ribonucleoprotein (RNP) complex. |

Title | Introduction of virulence markers in PB2 of pandemic swine-origin influenza virus does not result in enhanced virulence or transmission |
Author | Sander Herfst,Salin Chutinimitkul,Jianqiang Ye,Emmie de Wit,Vincent J Munster |
Evidence | Mutations E627K and D701N in the PB2 protein have previously been identified as determinants of avian and pandemic influenza virus virulence in mammals. |
