calcium/calmodulin-dependent protein kinase IV

Calcium/calmodulin-dependent protein kinase IV (CaMKIV) is an enzyme that helps regulate how cells respond to calcium signals. When calcium levels inside the cell rise, calcium binds to a protein called calmodulin, forming a complex that activates CaMKIV. Once active, CaMKIV can modify other proteins by adding phosphate groups, which can influence gene expression and cellular activities like learning, memory, and immune responses. It plays a key role in transmitting signals inside cells that affect growth and development, making it crucial for proper cell function and adaptation.
