Recombinant Influenza A Virus Polymerase Acidic Protein (PA), N-His

Influenza A virus polymerase acidic protein (PA) is a key component of the viral RNA polymerase complex, which is responsible for replicating and transcribing the viral genome. This protein plays a critical role in the initiation of viral RNA synthesis and is essential for the virus's ability to infect host cells and propagate. The PA subunit, along with PB1 and PB2, forms a functional trimeric complex that carries out these vital functions within the host's nucleus. In veterinary medicine, understanding the function of PA is crucial for developing strategies to control and prevent influenza A virus infections in animals, which can also have implications for human health due to the potential for cross-species transmission. The PA protein is also a target for antiviral drugs, making it an important protein in the development of treatments for influenza A virus infections.
