PB2 is a subunit of the RNA-dependent RNA polymerase which is responsible for replication and transcription of virus RNA segments. This entry represents the so-called '627 domain', named because it contains the host specificity residue 627 which is a lysine in human Influenza A virus and a glutamate in avian strains [1]. It contains a large positively charged region, consistent with its ability to bind RNA.	Domain
