Adenylyl Cyclase is an enzyme found in the cell membranes of many organisms. It plays a crucial role in cellular signaling by converting ATP (adenosine triphosphate) into cAMP (cyclic adenosine monophosphate), a secondary messenger that helps transmit signals within cells. This process is often triggered by hormones or neurotransmitters binding to specific receptors. The production of cAMP by Adenylyl Cyclase activates various protein kinases, leading to a cascade of cellular responses. These responses can influence processes such as metabolism, gene expression, and cell growth. Dysregulation of Adenylyl Cyclase activity is associated with several diseases, highlighting its importance in maintaining cellular function.
