    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.
