MRAP and infection: During a lytic infection, where β2.7 is also the most highly transcribed viral gene, accounting for approximately 46.8% of polyadenylated viral RNA at 72 h post infection (h.p.i) [13], it is known to protect lytically infected cells from apoptosis induced by rotenone by its interaction with mitochondrial Complex I, but the mechanism of how this protection occurs has not yet been identified [14].
