Calmodulin-activated adenylate cyclase

Calmodulin-activated adenylate cyclase is an enzyme that helps convert a molecule called ATP into another molecule called cyclic AMP (cAMP), which plays a crucial role in cell signaling. Calmodulin is a protein that binds calcium ions; when calcium levels rise in a cell, calmodulin activates adenylate cyclase. This process is important for various physiological functions, such as heart rate regulation and muscle contraction, as cAMP acts as a signaling messenger that influences many cellular responses. Essentially, this enzyme is a key player in how cells communicate and respond to changes in their environment.
