Since simian virus 40 ( SV40 ) large T antigen and human papillomavirus type 16 ( HPV16 ) E7 protein also bind host regulatory factors , we investigated whether these viral proteins can complement E1A mutants which are defective in early gene activation .
 GENE: simian virus 40 ( SV40 ) large T antigen; GENE: human papillomavirus type 16 ( HPV16 ) E7 protein; GENE: E1A mutants
