DNA sequences of polyoma virus early deletion mutants.

N Smolar, B E Griffin
PMCID: PMC171234  PMID: 6264166

Abstract

The DNA sequences of four "early" viable deletion mutants of polyoma virus have been determined. Two of these (dl-8 and dl-23) are mutants with deletions in the region of the genome that codes for parts of both large and middle T-antigens, and two (dl-6 and dl-28) are mutants with deletions around the viral origin of replication. The former mutants have altered transformation properties relative to wild-type virus, and dl-8 appears to be replication deficient (B. E. Griffin and C. Maddock, J. Virol. 31:645-656, 1979). Sequences are discussed in terms of the altered phenotypes observed for the various mutants, the DNA structures and protein sequences that are affected by the deletions, and how these might affect the biological properties of the mutants.
