To help in identifying functional domains within Ad5 E1A proteins, we have constructed a series of mutants that create deletions throughout these products. We have also produced several mis-sense point mutations in the unique 13 S mRNA region. These mutated E1A regions have been tested in plasmid form for their ability to activate transcription of an E3-promoted CAT gene. From the results, a major domain for transactivation has been identified. This begins between residues 138 and 147, ends between residues 188 and 204, and encompasses the unique 13 S region. This domain is sensitive to mis-sense mutations. Transactivation was unaffected by small deletions in the N-terminal half of E1A proteins between residues 4 and 138, but was destroyed when this whole region was deleted. The C-terminal 71 residues may affect transactivation, but the results with the mutant in which this region was deleted were variable. The results obtained with these mutants are discussed in relation to the transactivation obtained by J. W. Lillie et al. [(1987). Cell 50, 1091-1100] with a synthetic peptide similar to the domain described here.
