Polyoma virus DNA: Sequence from the late region that specifies the leader sequence for late mRNA and codes for VP2, VP3, and the N-terminus of VP1.

ABSTRACT

The DNA sequence of part of the late region of the polyoma virus genome is presented. This sequence of 1,348 nucleotide pairs encompasses the leader region for late mRNA and the coding sequence for the two minor capsid proteins VP2 and VP3. The coding sequence for the N-terminus of the major capsid protein overlaps the C-terminus of VP2/VP3 by 32 nucleotide pairs. From the DNA sequence the sizes and sequences of VP2 and VP3 could be predicted. Potential splicing signals for the processing of late mRNA's could be identified. Comparisons are made between the sequence of polyoma virus DNA and corresponding regions of simian virus 40 DNA.
