HSV-1 VP11/12-mediated initiation of Src family kinase-PI3 kinase-Akt signalling

  • Herpes simplex virus type 1 is a ubiquitous human virus that causes cold sores and, increasingly, genital herpes. Upon virion-cell fusion, tegument proteins diffuse into host cytosol and, as such, are poised to remodel signalling pathways. Tegument proteins of interest here are virion protein 11/12 (VP11/12) and US3 protein kinase (US3PK), for its potential role in VP11/12 regulation. Wagner and Smiley (2011) posited a model wherein VP11/12 commandeers Lck to activate Akt. This study tests this model using various in vitro assays to dissect VP11/12 interaction with the Lck SH2 domain. My findings support the Wagner-Smiley model. To address curiosities in prior US3PK characterization, I generated US3-null mutants from wild-type and UL46-null viruses to produce US3- and UL46-null single and double knock-outs derived from KOS-37. Preliminary analysis of US3 mutants shows US3PK-dependent VP11/12 modification. These mutants allow for further exploration of US3PK-VP11/12 interplay.
