However, we show that mutant forms of E1A that no longer bind p300/CBP can still interact directly with Stat1 (via E1A N-terminal and Stat1 C-terminal residues ) and block IFNgamma-driven, Stat1 -dependent gene activation and consequent function during early-phase infection in the natural host cell .
 ( protein: Stat1, None) , ( protein: E1A, None) , ( protein: p300/CBP, None) , ( protein: Stat1, None) , ( cell type: natural host cell, None)
