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.
Polymerase basic protein 2 (PB2) is a subunit of the RNA-dependent RNA polymerase of Orthomyxovirus Influenza A virus (IAV) which performs transcription of viral mRNAs by cap-snatching, a processes that generated capped primers by host pre-mRNA bindi ...
Polymerase basic protein 2 (PB2) is a subunit of the RNA-dependent RNA polymerase of Orthomyxovirus Influenza A virus (IAV) which performs transcription of viral mRNAs by cap-snatching, a processes that generated capped primers by host pre-mRNA binding, mediated by PB2 [1]. This protein has two domains, the cap-binding and the so-called '627-domain'. This entry represents the cap-binding domain and includes PB2 from Thogoto (THOV) virus, which is similar to IAV [1].

Influenza virus encodes a large, multidomain RNA-dependent RNA polymerase that can both transcribe and replicate the viral RNA genome. In influenza virus, the polymerase is composed of three polypeptides: PB1, PB2 and PA/P3. PB1 houses the polymerase active site, whereas PB2 and PA/P3 contain, respectively, cap-binding [1] and endonuclease domains required for transcription initiation by cap-snatching [2]. This entry represents the helical domain of Flu PB2 protein.
