We show that the BR3 sequence contains a novel negative regulatory element located at positions -90 to -79 of the hIL-5 promoter , which binds Oct1 , octamer-like , and YY1 nuclear factors .
 ( protein: octamer-like, None) , ( protein: YY1 nuclear factors, None) , ( DNA: hIL-5 promoter, None) , ( protein: YY1, None) , ( DNA: BR3, None) , ( DNA: negative regulatory element, None) , ( protein: Oct1, None)
