WebMay 14, 2024 · Second messengers are molecules that relay signals received at receptors on the cell surface — such as the arrival of protein hormones, growth factors, etc. — to target molecules in the cytosol and/or nucleus. But in addition to their job as relay molecules, second messengers serve to greatly amplify the strength of the signal. WebIntracellular receptors are generally reserved for highly lipid-soluble drugs such as anti-inflammatory steroids, thyroid hormones, and vitamin A or D. These receptors belong to a superfamily of DNA-binding proteins. When activated by the binding of an agonist, they translocate to the nucleus of the cell and recognize specific binding sites along the …
