Abstract
The simian virus 40 large T antigen (T) is a multifunctional phosphoprotein. We found that T-dependent simian virus 40 DNA replication is substantially inhibited by okadaic acid. This result suggests that DNA replication is activated by dephosphorylation in vitro. We show here that the target activated by dephosphorylation, which stimulates DNA replication, is T and that the phosphatase involved is protein phosphatase 2A.
