      This is clearly shown during SV40 productive infections where T antigen levels rise during the first 24 h postinfection, but then reach a steady-state level. Mutation of the T antigen binding sequences in the early promoter eliminate this autoregulation and lead to constituitively high levels of T antigen.

      TAg is capable of inducing malignant transformation of a variety of cell types. The transforming activity of TAg is due in large part to its perturbation of the retinoblastoma and p53 tumor suppressor proteins. In addition, TAg binds to several other cellular factors, including the transcriptional co-activators p300 and CBP, which may contribute to its transformation function.

      Binds two adjacent sites in the SV40 origin. The replication fork movement is facilitated by Large T antigen helicase activity. Activates the transcription of viral late mRNA, through host TBP and TFIIA stabilization. Interferes with histone deacetylation mediated by HDAC1, leading to activation of transcription.
