Human Hprt Gene

The enzyme hypoxanthine phosphoribosyltransferase (HPRT) catalyzes the metabolic salvage of the purine bases hypoxanthine and guanine. We previously characterized the genomic structure of the human HPRT gene and described its promoter sequence. In this report, we identify cis-acting transcriptional control regions of the human HPRT gene by linking various 5'-flanking sequences to the bacterial chloramphenicol acetyltransferase gene. The sequence from positions -219 to -122 relative to the translation initiation site is required for maximal expression of this gene, and it functions equally in both normal and reverse orientations. In addition, a cis-acting negative element is present in the region spanning from positions -570 to -388. This negative element can also repress promoters of heterologous genes, such as those of adenosine deaminase and dihydrofolate reductase, which are structurally and functionally similar to the human HPRT promoter. Furthermore, this repressor element functions independently of its orientation but appears to be distance dependent. In vivo competition assays demonstrated that the trans-acting factor(s) that binds to this negative element specifically inhibits human HPRT promoter activity. Taken together, these data localize cis-acting sequences important in the regulation of human HPRT gene expression and should allow the study of protein-DNA interactions which modulate the transcription of this gene.
