Calmodulin-binding proteins
Calmodulin-binding proteins are proteins that interact with calmodulin, a small but vital protein that helps cells respond to calcium levels. When calcium enters a cell, it binds to calmodulin, changing its shape and allowing it to attach to these binding proteins. This interaction triggers various cellular processes, such as muscle contraction, regulating enzymes, and controlling cell growth. Essentially, calmodulin acts like a switch that helps transmit signals within the cell, influencing many important functions in the body, from heartbeats to brain activity.
