Receptors for steroid hormones: membrane-associated and nuclear forms

Abstract:
Steroid hormones are now recognized to act through both nuclear and membrane-associated receptors. In this review we focus on receptors for estrogen and the vitamin D metabolite 1,25-dihydroxyvitamin D(3). While the nuclear receptors are part of a 'superfamily' with common structural elements, membrane receptors are more diverse, ranging from variants of the nuclear forms to unrelated proteins. We conclude that both rapid (membrane-initiated) actions, as well as regulation of gene transcription, are necessary to explain the complex actions of steroid hormones on target cells.

Types of Hormones
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...
