1. Behaviour of influenza A viruses differentially expressing segment 2 gene products in vitro and in vivo.

    Journal of General Virology 93(Pt 4):840 (2012) PMID 22190016

    The influenza A virus genome comprises eight segments of negative-sense RNA that encode up to 12 proteins. RNA segment 2 encodes three proteins, PB1, PB1-F2 and N40, that are translated from the same mRNA by ribosomal leaky scanning and reinitiation. PB1 is a subunit of the trimeric viral RNA po...
