Annotationa metab concept; IM; coord with substance acting as the second messenger (IM) with / physiol or / antag as applicable; DF: SECOND MESSENGERS
Scope NoteSystems in which an intracellular signal is generated in response to an intercellular primary messenger such as a hormone or neurotransmitter. They are intermediate signals in cellular processes such as metabolism, secretion, contraction, phototransduction, and cell growth. Examples of second messenger systems are the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system.
