Simian virus 40 (SV40) small t antigen inhibits SV40 DNA replication in vitro.

RESUMO

We describe a biochemical function of simian virus 40 small t antigen, the inhibition of simian virus 40 large T antigen-mediated viral DNA replication in an in vitro replication system. Our results suggest that in this system, small t antigen prevents protein phosphatase 2A-mediated activation of large T antigen.
