Multimerization of ICP0, a herpes simplex virus immediate-early protein
Abstract
ICP0, a herpes simplex virus immediate-early gene product, is a highly phosphorylated nuclear protein that is a potent activator of virus and host genes. Using biochemical and genetic assays employing plasmids encoding mutant forms of ICP0 and a recombinant adenovirus that expresses ICP0, we mutant forms of ICP0 and a recombinant adenovirus that expresses ICP0, we provide evidence that the protein multimerizes. Some mutant forms of ICP0 were transdominant and interfered with activation of a target reporter gene or with complementation of an ICP0-minus virus.
