The downstream regulatory sequence of the adenovirus type 2 major late promoter is functionally redundant.

Mutagenesis of promoter sequences and oligonucleotide competition assays have been used to demonstrate the late-phase-specific stimulation of the adenovirus type 2 major late promoter is mediated by functionally redundant elements located between positions +75 and +125. These octamer motif-related sequences are recognized by multiple factors.
