Calcium-binding protein

Calcium-binding proteins are specialized proteins that can attach to calcium ions (Ca²⁺) in the body. They play crucial roles in various biological processes, such as muscle contraction, nerve signaling, and cellular communication. By binding to calcium, these proteins help regulate its levels and ensure that cells function properly. Common examples include calmodulin, which helps control many cellular activities in response to calcium changes, and parvalbumin, important for muscle function. Overall, calcium-binding proteins are essential for maintaining the balance and functionality of various physiological processes.
