Prevalence of PB1-F2 of influenza A viruses

25 Jan 2007

Abstract excerpt

PB1-F2 is a pro-apoptotic polypeptide of many influenza A virus (FLUAV) isolates encoded by an alternative ORF of segment 2. A comprehensive GenBank search was conducted to analyse its prevalence. This search yielded 2226 entries of 80 FLUAV subtypes. Of these sequences, 87 % encode a PB1-F2 polypeptide greater than 78 aa. However, classic swine influenza viruses and human H1N1 isolates collected since 1950...
