Disruption of PML Subnuclear Domains by the Acidic IE1 Protein of Human Cytomegalovirus Is Mediated through Interaction with PML and May Modulate a RING Finger-Dependent Cryptic Transactivator Function of PML

Abstract excerpt

Both of the major immediate-early (IE) proteins IE1 and IE2 of human cytomegalovirus (HCMV) as well as input viral DNA and sites of viral IE transcription colocalize with or adjacent to punctate PML domains (PML oncogenic domains [PODs] or nuclear domain 10) in the nucleus within the first few hours after infection of permissive human fibroblasts. However, colocalization of IE1 and PML in PODs is only transient,...
