It is rapidly broken down by phosphodiesterases when the time comes for the signal to be terminated, and it usually acts by stimulating protein kinases.
It is similar to forskolin in one case in that it directly stimulates tubules in vitro, because it is actively transported into the cytoplasm. In many organisms it is generated by hormone action on a receptor to activate the involved adenylate cyclase enzyme.

FTP, name this most common second messenger in the body, a cyclic derivative of ATP.
