Adenylate cyclase is stimulated by G proteins, and by forskolin, as well as other class-specific substrates:
Isoforms I, III and VIII are also stimulated by Ca2+/calmodulin.
Isoforms V and VI are inhibited by Ca2+ in a calmodulin-independent manner.
In neurons, adenylate cyclases are located next to calcium ion channels for faster reaction to Ca2+ influx; they are suspected of playing an important role in learning processes. This is supported by the fact that adenylate cyclases are coincidence detectors, meaning that they are only activated by several different signals occurring together.

so does that mean that G protein only stimulates adenyll cyclase but it aint composed of it????

i feel that g protein and adenyl cyclase are different entity altogether.g protein has a Gs subtype which stimulates the adenyl cyclase thats all.
