What is the Origin of Nuclear Receptors?

The term is descriptive, combining 'nuclear,' referring to their action within the cell nucleus, with 'receptors,' indicating their function as binding proteins for signaling molecules, derived from the Latin recipere meaning "to receive." This classification arose from the discovery that steroid hormones did not utilize cell surface receptors but instead crossed the plasma membrane to interact with intracellular binding sites.

What is the Mechanism of Nuclear Receptors?

Steroid hormones, being lipid-soluble, passively diffuse across the cell membrane and bind to their specific nuclear receptor, often causing a conformational change. This activation event typically promotes the receptor-ligand complex to translocate to the nucleus, if not already there. Once in the nucleus, the complex binds to specific DNA sequences known as Hormone Response Elements (HREs) in the promoter regions of target genes, either recruiting coactivator or corepressor proteins to initiate or inhibit gene transcription, respectively, thus directly altering the cell's protein synthesis profile.

Nuclear Receptors

Meaning

A class of ligand-activated transcription factors located within the cell cytoplasm or nucleus that, upon binding to specific lipophilic signaling molecules, directly regulate the transcription of target genes. These receptors are the primary mediators of the effects of steroid hormones, thyroid hormones, and vitamins A and D, making them central to endocrinology and metabolic regulation. Their function allows hormones to exert profound and long-lasting effects on cellular phenotype.
