Hormone Receptor

Meaning

A Hormone Receptor is a protein structure, typically located on the cell surface or within the cytoplasm or nucleus, that specifically binds to a signaling hormone molecule. This binding event initiates a cascade of intracellular events that ultimately alter gene expression or cellular function in response to the endocrine signal. Receptors are the essential molecular interfaces that translate hormonal messages into biological action within target tissues. Their presence and affinity determine tissue responsiveness.
