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 CAP binding domain [2].
