Abstract

We have isolated a simian virus 40 deletion mutant, F8dl, that lacks the sequences from 0.168 to 0.424 map units. The deleted sequences represent over 60% of the coding region for large T antigen. Despite this deletion, F8dl abortively transformed rat cells as efficiently as wild-type simian virus 40. From this result, we conclude that the region of the simian virus 40 genome between 0.168 and 0.424 map units is not essential for abortive transformation. Since abortive transformation requires the expression of the simian virus 40 maintenance functions, we also infer that the sequences deleted from F8dl are not required to maintain transformation.
