Human endothelin-converting enzyme (ECE)-1, the key enzyme in endothelin biosynthesis, shows broad cell and tissue expression within the cardiovascular system. Expression of ECE-1c, which represents the major ECE-1 isoform, is directed by an alternative promoter, but the mechanisms of ECE-1c promoter regulation are largely unknown. As ECE-1c transcription is initiated from several start sites, we hypothesized that the ECE-1c promoter functions as a housekeeping promoter.
