Abstract

The adenovirus (Ad) genome complexed with viral core proteins designated Ad core is the template for transcription of early genes and the first round of replication in Ad-infected cells. A cellular protein designated template-activating factor-I (TAF-I) is found to be involved in remodeling of the Ad core in vitro. Here we found that TAF-I interacts with the Ad DNA through core protein VII in infected cells in early phases of infection. In vitro binding assays using recombinant proteins showed that TAF-I forms ternary complexes with DNA-protein VII complexes.
