WebFunction [ edit] ADCY1 is a calmodulin-sensitive adenylyl cyclase. In terms of function, It may be involved in regulatory processes in the central nervous system; specifically, it may play a role in memory acquisition and learning. It is inhibited by the G protein beta and gamma subunit complex. [7] References [ edit] WebThe results suggest that dopamine, calmodulin, and GppNHp are modulators of a common component of adenylate cyclase activity, and this component is regulated by light.
