title: The rat S-adenosylhomocysteine hydrolase promoter.
abstract: The 1.2-kb DNA sequence flanking the transcription start of the AdoHcy hydrolase gene was cloned into the luciferase reporter plasmid pGL3-basic, and promoter activity was measured in transiently transfected CHO cells. Deletion analysis showed that most promoter activity was located within a 153 bp fragment immediately upstream from the predominant transcription start. The 153 bp fragment includes sites for AP-2, glucocorticoid-responsive element, SP-1, and a TATA-like sequence TATTTAAA. Mutational analysis demonstrated that the SP-1 site nearest the start of transcription contributed significantly to promoter activity, whereas, the other elements, including the appropriately positioned TATTTAAA sequence, had little affect on promoter activity.
