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 | Rapid spread of influenza A(H1N1)pdm09 viruses with a new set of specific mutations in the internal genes in the beginning of 2015/2021 epidemic season in Moscow and Saint Petersburg (Russian Federation) |
| Author | Andrey Komissarov,Artem Fadeev,Maria Sergeeva,Sergey Petrov,Kseniya Sintsova |
| Evidence | Whole-genome analysis revealed a composition of specific mutations in the internal genes (D2E and M83I in NEP, E125D in NS1, M105T in NP, Q208K in M1, and N204S in PA-X) that probably emerged before the beginning of 2015/2021 epidemic season. |
