Abstract

The influenza A virus PB1-F2 protein predominantly localizes in the mitochondria of virus-infected cells. A series of cDNAs encoding N- and C-terminal deletion mutants and site-directed mutagenesis of the basic residues of PB1-F2 appended to 3xFLAG revealed the domain from residues 46 to 75 to be both necessary and sufficient for mitochondrial targeting. In addition, the subdomain residues 63-75 and both Lys73 and Arg75 are minimally required for mitochondrial localization. Transfection of untagged- and 3xFLAG tagged-PB1-F2 into Vero, HeLa and MDCK cells changed the mitochondrial morphology from a filamentous to a dotted structure and suppressed the inner-membrane potential.
