Herpes simplex virus type 1 (HSV-1) regulatory protein ICP0 stimulates lytic infection and the reactivation of quiescent viral genomes. These roles of ICP0 require its RING finger E3 ubiquitin ligase domain, which induces the degradation of several cellular proteins, including components of promyelocytic leukemia nuclear bodies and centromeres. ICP0 also(More)
Herpes simplex virus type 1 immediate-early regulatory protein ICP0 stimulates lytic infection and reactivation from latency, processes that require the ubiquitin E3 ligase activity mediated by the RING finger domain in the N-terminal portion of the protein. ICP0 stimulates the production of polyubiquitin chains by the ubiquitin-conjugating enzymes UbcH5a(More)
The ability to destroy a particular protein at a particular time is central to the regulation of many cellular processes. Selective proteolysis in eukaryotic cells is carried out primarily by the ubiquitin-proteasome pathway. Attachment of a ubiquitin polymer to an unwanted protein causes it to be degraded by the proteasome. Several classes of enzyme, known(More)
