Calmodulin-dependent protein kinase (CaMK)

Calmodulin-dependent protein kinase (CaMK) is an enzyme that plays a crucial role in cellular signaling. It activates in response to rising calcium levels in cells. Once activated, CaMK modifies other proteins, which can affect various cellular processes such as muscle contraction, neurotransmitter release, and gene expression. Essentially, it helps cells respond to changes in their environment by regulating important activities, ensuring proper functioning of various systems in the body, from the heart to the brain. Its activity is vital for many physiological functions and is a key player in how cells communicate and adapt.
