The enzyme 25-hydroxyvitamin D 1-hydroxylase (CYP27B1) is the rate limiting enzyme in the two-step activation process of Vitamin D to its active form 1,25-dihydroxyvitamin D (1,25D) and is located in the mitochondrial fraction of the proximal tubular cells of the kidney. More recently CYP27B1 activity and expression have also been identified in a number of(More)
The renal enzyme 25-hydroxyvitamin D 1alpha-hydroxylase (CYP27B1), responsible for the synthesis of circulating. 1,25-dihydroxyvitamin D (1,25D), is also expressed in a number of non-renal tissues. The regulation of CYP27B1 expression by the short flanking promoter outside the kidney is, however, largely unknown. We have used a transgenic mice expressing(More)
