Abstract: Fragments of the human glutathione S-transferase pi gene and 15 kb of its 5' flanking region have been fused to the chloramphenicol acetyl transferase (CAT) reporter gene. Transfection into a number of human cell lines (Hela, HepG2, MCF7 and EJ) has demonstrated that the AP1 binding site, located between nucleotides -58 and -65 (Cowell et al. 1988. Biochem. J. 255, 79-83), is essential for basal level promoter activity. We have also identified a positive cis-acting DNA element between nucleotides +8 and +72 which seems to be part of the promoter. No other regulatory activity was identified within the 17 kb analyzed
