肾上腺氧还蛋白是一种铁硫蛋白,作为所有线粒体形式的细胞色素P450的电子传递中间体。为了便于研究肾上腺素还蛋白的调控,我们克隆了人肾上腺素还蛋白基因并确定了其结构。它的长度超过20 kb,包含4个外显子和3个内含子。第一个外显子编码60个氨基酸的信号肽,指导蛋白质转运到线粒体内基质。另外三个外显子编码124个氨基酸的成熟肽。第三个外显子编码含有铁硫中心和结合电子传递链其他组分的结构域的蛋白质部分。通过引物延伸和S1核酸酶图谱确定转录起始位点。该基因的5′侧翼区包含典型启动子,包括核苷酸位置-30的TATA盒和核苷酸位置-60和-100的两个GC盒。核苷酸-234至-252处的序列也与糖皮质激素反应元件和雌激素反应元件高度同源。
Adrenodoxin is an iron–sulfur protein that serves as an electron transport intermediate for all mitochondrial forms of cytochrome P450. To facilitate studying the regulation of adrenodoxin, we have cloned and determined the structure of the human adrenodoxin gene. It spans more than 20 kb, containing four exons and three introns. The first exon encodes the 60-amino-acid signal peptide, directing transport of the protein into the inner mitochondrial matrix. The mature peptide of 124 amino acids is encoded by the other three exons. The third exon encodes the portion of the protein containing the iron–sulfur center and a domain which binds other components of the electron transport chain. The transcriptional start sites were determined by primer extension and S1nuclease mapping. The 5′-flanking region of this gene contains canonical promoters including a TATA box at nucleotide position −30 and two GC boxes at nucleotide positions −60 and −100. The sequence at nucleotides −234 to −252 is also highly homologous to the glucocorticoid-responsive element and the estrogen-responsive element.
