Plays a role in viral DNA packaging and nucleocapsid assembly. Promotes viral gene transcription during the late stage of infection while it is non-essential for the basal level of viral gene transcription. Interacts with protein AC132. Within the host cell, the majority of P6.9 is distributed near the inner nuclear membrane. Present in both the budded virus (BV) and the occluded virus (OV). The occluded form allows the virus to be transmitted from insect to insect through ingestion of contaminated food while the budded form is responsible for the dissemination of infection throughout the insect host. Phosphorylated.
