Second messengers are intracellular signaling molecules released by the cell in response to exposure to extracellular signaling molecules—the first messengers. (Intercellular signals, a non-local form of cell signaling, encompassing both first messengers and second messengers, are classified as autocrine, juxtacrine, paracrine, and endocrine depending on the range of the signal.) Second messengers trigger physiological changes at cellular level such as proliferation, differenti… WebThe levels of cellular cyclic AMP are generally regulated by changes in the activity of adenylate cyclase (AC), the enzyme responsible for the synthesis of this second messenger. This enzyme is an integral membrane effector protein that utilizes ATP as a substrate and magnesium as a cofactor to form cyclic AMP and inorganic phosphate.
