We have constructed an adenovirus type 5 (Ad5) E1A mutant, dl1119/520, that produces essentially only exon 2 of the major E1A proteins. In infected primary baby rat kidney cells, this mutant induced expression of the E1B 55-kDa protein, and in infected human KB cells, it induced expression of this protein, the E2A 72-kDa protein, and hexon. In KB cells, this mutant grew substantially better than Ad5 dl312, which lacks E1A, and as well as Ad5 dl520, an E1A mutant producing only the 243-residue protein. Read More
