These results lead to a general model for the synergistic function of activation domains in Oct-1 and OCA-B (mediated by the combined action of the multiple USA components ) and, further, suggest a functional redundancy in general coactivators .
 ( protein: OCA-B, None) , ( protein: Oct-1, None) , ( protein: general coactivators, None)
