The specialised part of a cell which recognises, binds to and is activated by a biological or synthetic messenger (called a ligand). Receptor-ligand binding produces a biological response. Most receptors are found on the cell surface, apart from receptors for steroids and steroid hormones which are found in the cell nucleus.
