Calmodulinregulated

Calmodulin-regulated processes refer to biological activities that are influenced by the presence and activity of calmodulin, a calcium-binding protein. Calmodulin plays a crucial role in signal transduction pathways, particularly in response to calcium ions. When calcium levels rise, calmodulin binds to calcium ions, undergoing a conformational change that exposes hydrophobic pockets. These pockets can then interact with various target proteins, activating or deactivating them. This interaction is essential for the regulation of numerous cellular processes, including muscle contraction, neurotransmitter release, and gene expression. Calmodulin's ability to bind calcium and regulate target proteins makes it a key mediator in cellular signaling, influencing a wide range of physiological and pathological processes.
