Target type: molecularfunction
Binding to thyroxine (T4) or triiodothyronine (T3), tyrosine-based hormones produced by the thyroid gland. [GOC:rph]
Thyroid hormone (TH) binding is a critical molecular function that involves the interaction of TH with specific proteins, primarily nuclear receptors, to regulate gene expression and influence various physiological processes. TH, consisting of thyroxine (T4) and triiodothyronine (T3), plays a crucial role in development, metabolism, and the regulation of numerous cellular functions. The binding of TH to its receptors initiates a cascade of events that ultimately alters gene transcription. The process begins with the transport of TH from the bloodstream into target cells, where it binds to intracellular proteins, primarily thyroxine-binding globulin (TBG) and albumin. Once inside the cell, T4 undergoes deiodination to T3, which is the biologically active form of the hormone. T3 then binds to nuclear receptors, specifically thyroid hormone receptors (TRs), forming a heterodimer complex with the retinoid X receptor (RXR). This heterodimer complex binds to specific DNA sequences known as thyroid hormone response elements (TREs) located in the regulatory regions of target genes. The binding of the TR-RXR heterodimer to TREs triggers a conformational change in the receptor complex, leading to the recruitment of coactivator proteins and the initiation of gene transcription. The coactivator proteins facilitate the assembly of the transcriptional machinery, enabling the production of messenger RNA (mRNA) for the target gene. The resulting mRNA is then translated into protein, leading to the expression of the target gene and the modulation of its corresponding function. This intricate molecular function of TH binding plays a crucial role in regulating a wide range of biological processes, including growth and development, metabolism, cardiovascular function, and the nervous system. Disruptions in TH binding can lead to various disorders, highlighting the importance of this essential molecular function in maintaining homeostasis and overall health.'
