to directly determine the role of the 13s e1a encoded 289aa protein and the 12s e1a encoded 243aa protein in initiating an oncogenic phenotype in adenovirus-transformed cref cells , we generated transformed cell lines following infection with the ad2 mutant pm975 , which synthesizes the 289aa e1a protein but not the 243aa protein , and the ad5 mutant h5dl520 and the ad2 mutant h2dl1500 , which do not produce the 289aa e1a protein but synthesize the normal 243aa e1a protein .
