| Description | Purity ~90% (SDS-PAGE). 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. In addition of its function in viral transcription, PA also plays an essential role in viral RNA synthesis and promotes the formation of the trimeric polymerase complex. Source: Recombinant protein corresponding to aa1-716 from influenza A virus Polymerase Acidic Protein, fused to His-Tag at N-terminal, expressed in Yeast. Molecular Weight: ~84.7kD AA |
