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. |
