Study Notes
Hormone Receptors
- Steroid hormones interact with intracellular receptors.
Binding of Hormones
- Polypeptide and protein hormones bind to receptors on the surface of cells to generate a signal.
Receptor Function
- The recognition domain of a receptor is responsible for recognizing and binding to specific hormones.
Signal Generation
- The ligand-receptor complex of steroid hormones provides a signal by binding to specific DNA sequences, which in turn affects gene expression.
Functional Domains
- Steroid hormones and Thyroid hormone receptors have been identified to have functional domains for hormone recognition and signal generation.
