obsolete suppression by virus of host PKR activity by positive regulation of PKR nuclear localization true OBSOLETE. Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host PKR (protein kinase regulated by RNA) activity by promoting the localization of PKR in the nucleus. For example, human cytomegalovirus (HMCV) gene products directly interact with PKR and inhibit its activation by sequestering it in the nucleus, away from both its activator (cytoplasmic dsRNA) and its substrate, (eIF2alpha). suppression by virus of host PKR activity by nuclear sequestration of PKR suppression by virus of host PKR activity by positive regulation of PKR localization to nucleus The reason for obsoleting this term is that it is too specific. The exact molecular roles of the individual proteins should be captured separately. bf biological_process GO:0039582 suppression by virus of host PKR activity by sequestering of PKR in nucleus
