Overview

Adenylyl cyclase, E.C. 4.6.1.1, converts ATP to cyclic AMP and pyrophosphate. Mammalian membrane-bound adenylyl cyclases (nomenclature as approved by the NC-IUPHAR Subcommittee on Adenylyl cyclases [8]) are typically made up of two clusters of six TM domains separating two intracellular, overlapping catalytic domains that are the target for the nonselective activators forskolin, NKH477 (except AC9, [20]) and Gαs (the stimulatory G protein α subunit). Adenosine and its derivatives (e.g. 2',5'-dideoxyadenosine), acting through the P-site, appear to be physiological inhibitors of adenylyl cyclase activity [26]. Three families of adenylyl cyclase are distinguishable: calmodulin (CALM2, CALM3, CALM1, P62158)-stimulated (AC1, AC3 and AC8), Ca2+-inhibitable (AC5, AC6 and AC9) and Ca2+-insensitive (AC2, AC4 and AC7) forms.
