Abstract
We conducted a functional analysis of the promoter for the human ferritin heavy chain-encoding gene (pFERH) in HepG2 and HeLa cells. The activity of pFERH is equivalent in both cell types, despite their different ferritin (Fer) isotypes. Transfections of a series of 5'-deletion mutants indicate that pFERH activity is essentially dependent on two motifs. One of them, accounting for about 50% of the total transcriptional activity, is recognized by the RNA polymerase II transcription factor, Sp1, and the other by a low-affinity factor present in both the cell types analyzed.Entities:
