FIG 2.

Human adenovirus E4-ORF1 proteins form ternary complexes. (A) Cell extracts (300 μg of protein) from vector cells and the indicated HA-E4-ORF1 lines were immunoprecipitated with either p110α or Dlg1 antibody. Recovered proteins, as well as cell extract (input), were analyzed in immunoblot assays. (B) Cell extracts from vector cells and the indicated wt E4-ORF1 lines were immunoprecipitated with Dlg1 antibody as described for panel A, and recovered proteins, as well as cell extract (input), were analyzed in immunoblot assays.
