Herpes Simplex Virus is Akt-ing in translational control

Abstract: All viruses depend on the cellular protein synthesis machinery for the production of viral proteins. Thus, viruses have evolved a variety of strategies to avoid innate host responses that inhibit protein synthesis. In this issue of Genes & Development, Chuluunbaatar and colleagues (pp. 2627–2639) demonstrate that Herpes Simplex Virus-1 counteracts this response through viral kinase Us3, which mimics cellular kinase Akt to phosphorylate and repress tuberous sclerosis complex 2 (TSC2), resulting in the activation of mammalian target of rapamycin complex 1 (mTORC1) and enhancement of mRNA translation.

Key Words: Translational control • herpesvirus replication • viral kinase • mTOR activation • Akt signaling
