We present a model in which HMG-I(Y) alters DNA conformation to allow binding of repressor proteins , and in which the relative amount of HMG-I(Y) helps to determine the repressive state of the beta-globin gene .
 ( protein: HMG-I(Y), None) , ( protein: repressor proteins, None) , ( DNA: beta-globin gene, None)
