Most of the known effects of aldosterone are mediated by the mineralocorticoid receptor, an intracellular receptor belonging to the steroid/thyroid hormone/retinoic acid receptor superfamily. We determined the genomic structure of the human MR (hMR) and identified 10 exons in the gene, including two exons (1α and 1β) that encode different 5'-untranslated sequence. Expression of the two different hMR variants is under the control of two different promoters that contain no obvious TATA element, but multiple GC boxes. Our results indicate that hMR expression is regulated by alternative promoters perhaps in a tissue- or developmental-specific manner.
