title: Mutation affecting late gene expression in polyoma virus maps in the late region.
abstract: A mutation in polyoma virus strain 3049 which results in the overproduction of capsid proteins has been mapped to the late region of the genome between the HindIII site at 45.0 map units and the BamHI site at 58.6 map units. This region contains the coding sequence for VP3 and a portion of VP2, but does not include the late promoters or the coding sequence for the late leaders. The possible role of VP2 or VP3 in the regulation of genetic expression in polyoma virus is discussed.
