Sequences in influenza A virus PB2 protein that determine productive infection for an avian influenza virus in mouse and human cell lines.
Reverse genetics was used to analyze the host range of two avian influenza viruses which differ in their ability to replicate in mouse and human cells in culture. Engineered viruses carrying sequences encoding amino acids 362 to 581 of PB2 from a host range variant productively infect mouse and human cells.
