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. |

| Evidence | Presence in all Canadian sequences of non-clade 1 mutations (namely HA (P83S [P100S], and I321V [I338V]) and PA (P224S)) agrees with prior reports of limited geographic dissemination of clade 1 isolates. |
