previous studies have demonstrated that 4f2hc gene expression is induced during normal t-cell activation and that the activity of the gene is regulated , at least in part , by the interaction of a constitutively active 5'-flanking housekeeping promoter and a phorbol ester-responsive transcriptional attenuator element located in the exon 1-intron 1 region of the gene .
