Influenza RNA-dependent RNA polymerase subunit PB1 (IPR001407)

Short name: RNA_pol_PB1_influenza

Family relationships

None.

Description

Influenza RNA-dependent RNA polymerase is composed of three subunits; P1 (or PB1), P2 (or PA), and P3 (or PB2). There are two separate domains in the influenza virus PB1 protein involved in the interaction with the PB2 and PA subunits [PMID: 9348094, PMID: 8948635]. PB1 is the core of the complex and accounts for the polymerase activity [PMID: 10393191].
