Abstract

The Type I (mineralocorticoid) receptor has identical affinities in vitro for cortisol and aldosterone. It has been suggested that the selective role of aldosterone in regulating sodium homeostasis relies on the microsomal enzyme 11β-hydroxysteroid dehydrogenase (11-HSD). This enzyme converts cortisol to its inactive metabolite, cortisone, preventing cortisol from binding to the Type I receptor. We have isolated human cDNA clones encoding 11-HSD from a human testis cDNA library by hybridization with a previously isolated rat 11-HSD cDNA clone. The cDNA contains an open reading frame of 876 bases, which predicts a protein of 292 amino acids. The sequence is 77% identical at the amino acid level to rat 11-HSD cDNA. The mRNA is widely expressed, but the level of expression is highest in the liver. Hybridization of the human 11-HSD cDNA to a human-hamster hybrid cell panel localized the single corresponding HSD11 gene to chromosome 1. This gene was isolated from a chromosome 1 specific library using the cDNA as a probe. HSD11 consists of 6 exons and is at least 9 kilobases long. The data developed in this study should be applicable to the study of patients with hypertension due to apparent mineralocorticoid excess, a deficiency in 11-HSD activity.
