What is the Origin of Thyroid Receptor?

The discovery and characterization of the Thyroid Receptor (TR) are foundational achievements in endocrinology and molecular biology, confirming that thyroid hormones exert their primary effects by directly influencing the cell's genetic machinery. The term and its subtypes (TR-alpha and TR-beta) are central to understanding thyroid-related clinical conditions, including hypothyroidism and resistance syndromes.

What is the Mechanism of Thyroid Receptor?

Upon T3 binding, the Thyroid Receptor complex, which is typically bound to DNA in its inactive state, undergoes a conformational change. This change allows it to recruit co-activator proteins and release co-repressors, thereby initiating or enhancing the transcription of target genes. The resulting gene products include enzymes and proteins that increase mitochondrial respiration, regulate basal metabolic rate, and control the sensitivity of other hormone receptors, demonstrating the thyroid system's profound, widespread influence.

Thyroid Receptor

Meaning

The Thyroid Receptor is a nuclear receptor protein located within the nucleus of virtually every cell in the human body that binds to the active thyroid hormone, triiodothyronine (T3), to regulate gene expression. This receptor acts as a master switch, controlling the transcription of genes responsible for metabolism, growth, and development. Its proper function is essential for systemic energy production and cellular vitality.
