The promoter and first, untranslated exon of the human glucocorticoid receptor gene are GC rich but lack consensus glucocorticoid receptor element sites.

Glucocorticoid receptor mRNA is regulated by glucocorticoids. We found no consensus glucocorticoid response element, TATA box, or CAAT box but many GC boxes in approximately 3 kilobases of the 5'-flanking sequence of the human glucocorticoid receptor gene. We identified several transcription start sites, an untranslated exon 1, and the coding content of exon 2.
