Hormone-receptor complex formation is an important process in the regulation of cell function. The formation of this complex involves the binding of an extracellular hormone molecule to a specific membrane-bound receptor on the target cell. The hormone binds to the receptor, which then alters the receptor’s conformation and activates the receptor’s intracellular signaling pathways. The hormone-receptor complex then interacts with its downstream targets such as proteins, enzymes, and other molecules to bring about a change in the cell. The formation of this complex is important for the regulation of various physiological processes such as metabolism, development, and reproduction.
