Abstract: | A series of linker-scanning and deletion mutations was generated in the transactivating domain of the larger, 289-amino-acid-residue E1a protein of adenovirus type 2. Mutant genes were recombined into virus to assay the ability of the variant E1a proteins to activate expression of an E1a-dependent viral gene during infection. Results of assays performed at 32, 37, and 40 degrees C indicated that at least 2 of the 10 mutants tested showed limited temperature sensitivity for transactivation. |
