Protein detail:
Protein name | Polymerase PA |
Uniprot protein ID | C3W5X6 |
Protein length | 716 amino acids |
Protein description | PA Plays an essential role in viral RNA transcription and replication by forming the heterotrimeric polymerase complex together with PB1 and PB2 subunits. The complex transcribes viral mRNAs by using a unique mechanism called cap-snatching. It consists in the hijacking and cleavage of host capped pre-mRNAs. These short capped RNAs are then used as primers for viral mRNAs. The PB2 subunit is responsible for the binding of the 5' cap of cellular pre-mRNAs which are subsequently cleaved after 10-13 nucleotides by the PA subunit that carries the endonuclease activity. |

Title | Deep Sequencing Reveals Mixed Infection with 2009 Pandemic Influenza A (H1N1) Virus Strains and the Emergence of Oseltamivir Resistance |
Author | Elodie Ghedin,Jennifer Laplante,Jay DePasse,David E. Wentworth,Roberto P. Santos |
Evidence | Sanger consensus sequence assemblies of both samples also revealed a unique set of residues, compared with the pandemic H1N1/2009 virus strains available in public databases: specifically, a D199N mutation in the NA, a N55D mutation in the HA, and a R626K mutation in the polymerase. |
