Human polyomavirus JC promoter/enhancer rearrangement patterns from progressive multifocal leukoencephalopathy brain are unique derivatives of a single archetypal structure
1 Aug 1993
Abstract excerpt
We have compared the promoter/enhancer structure of human polyomavirus JC (JCV) isolates from 11 progressive multifocal leukoencephalopathy brains. The duplications and deletions of the regulatory region were different in each patient, and usually only one sequence was found in each. The sites of strand breakage in the promoter were not random; four or five preferred sites or areas exist. Alignment of the JCV...
