Abstract excerpt
Transcription of tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine biosynthesis, is regulated in a tissue-specific manner. We have identified sequences from -205 to -182 as the minimal enhancer for TH in pheochromocytoma cells using site-directed mutagenesis. This segment (TGATTCAGAGGCAGGTGCCTGTGA) is composed of an AP-1 motif (TGATTCA) and an overlapping 20 bp dyad whose core resembles an E...
