Differential Functions of Interferon-Upregulated Sp100 Isoforms: Herpes Simplex Virus Type 1 Promoter-Based Immediate-Early Gene Suppression and PML Protection from ICP0-Mediated Degradation

Abstract excerpt

Cells have intrinsic defenses against virus infection, acting before the innate or the adaptive immune response. Preexisting antiviral proteins such as PML, Daxx, and Sp100 are stored in specific nuclear domains (ND10). In herpes simplex virus type 1 (HSV-1), the immediate-early protein ICP0 serves as a counterdefense through degradation of the detrimental protein PML. We asked whether interferon...
