Identification and characterization of a small modular domain in the herpes simplex virus host shutoff protein sufficient for interaction with VP16

The herpes simplex virus transactivator VP16 and the virion host shutoff protein vhs are viral structural components that direct the activation of immediate-early gene expression and the arrest of host protein synthesis, respectively, during an infection. Recent studies show that VP16 and vhs physically interact with each other in vitro and in infected cells, suggesting that their respective regulatory functions are coupled. In this report, we …
