General description
TSH is a heterodimeric glycoprotein hormone secreted by the anterior pituitary gland. It consists of a common α-subunit shared with other glycoprotein hormones (FSH, LH, and hCG) and a hormone-specific β-subunit that confers receptor specificity. Native bovine TSH is structurally conserved across mammalian species and exhibits biological activity through interaction with the thyroid-stimulating hormone receptor (TSHR). As a glycosylated protein, its biological activity and stability are influenced by its carbohydrate moieties.
Application
Thyroid stimulating hormone has been used in:
- Studies of thyroid function and regulation
- Cell-based assays involving TSH receptor activation
- Endocrine signaling and hormone response studies
- Assays evaluating thyroid hormone biosynthesis
Biochem/physiol Actions
TSH binds to the TSH receptor (TSHR) on thyroid follicular cells, activating cAMP-dependent signaling pathways that regulate thyroid hormone synthesis and secretion (T3 and T4). It plays a central role in maintaining metabolic homeostasis and regulating growth and development.
Physical form
