The CCAAT element present in reverse orientation in this promoter region of the ferritin H-chain gene is necessary for binding and for gene activity, since a single point mutation is able to abolish the binding of HRF and the transcriptional activity in transfected cells .
 ( protein: HRF, None) , ( DNA: CCAAT element, None) , ( DNA: ferritin H-chain gene, None) , ( cell line: transfected cells, None) , ( protein: ferritin, None)
