SOX17 and SOX2 exhibit inverse heterodimerization preferences with OCT4 on canonical vs. compressed Sox/Oct DNA motifs; exchange of single amino acids at the OCT4 interaction interface converts SOX17 into a pluripotency reprogramming factor (SOX17EK) and abolishes SOX2 reprogramming activity (SOX2KE), demonstrating that the DNA-dependent Sox/Oct dimer configuration determines cell-fate outcome. |
