PB1 domain |
PBAN |
LGI3 |
||
This protein is encoded by influenza A virus (encoded by the +1 reading frame of gene PB1). The protein shows variable expression in individual infected cells, is degraded rapidly by a proteasome-dependent pathway degradation and localizes to mitochondria.
Exposure of cells to PB1-F2 causes cell death by apoptosis. Viruses with targeted mutations that interfere with PB1-F2 expression induce less extensive apoptosis in human monocytes than those with intact PB1-F2.
