Hormone Receptor

A hormone receptor is a receptor molecule that binds to a specific hormone. Receptors for peptide hormones tend to be cell surface receptors (built into the plasma membrane of cells, thus trans membrane), whereas receptors for steroid hormones are usually found within the cytoplasm (nuclear receptors). Upon hormone binding, the receptor can initiate multiple signaling pathways which ultimately lead to changes in the behavior of the target cells.
