Fig 7. Model for SINE RNA enhancement of viral gene expression.

Fig 7

SINE RNAs are robustly induced in response to MHV68 infection. Through both MAVS-dependent and independent mechanisms, they stimulate the activity of the IKKβ component of the NF-κB pathway. IKKβ is co-opted by the virus to promote phosphorylation of RelA/p65, blunting the NF-κB transcriptional response. Additionally, IKKβ phosphorylates RTA, thereby enhancing viral gene expression and replication.
