This protein-protein interaction does not require the simultaneous binding of Oct proteins to DNA, and high resolution footprinting of the Oct -DNA interaction reveals that binding of BOB.1/OBF.1 to Oct1 or Oct2 does not alter the interaction with DNA.
 protein: Oct1; protein: Oct proteins; DNA: Oct; protein: BOB.1/OBF.1; protein: Oct2
