The herpesvirus saimiri strain C488 genome contains five genes for
small nuclear RNAs, termed herpesvirus saimiri URNAs (or HSURs). Using
a cosmid-based approach, all HSURs were precisely deleted from the
genome. The mutant virus replicated at levels that were similar to
those of wild-type viruses in OMK cells. Although the HSURs are
expressed in wild-type virus-transformed human T-cell lines, the
deletion does not affect viral transformation in cell culture.
