Calcium sensors

Calcium sensors are molecules or proteins that detect calcium levels within cells or the body. They help monitor and respond to changes in calcium concentration, which is vital for functions like muscle movement, nerve signaling, and hormone release. These sensors can change their shape or brightness when calcium binds to them, allowing scientists or the body to measure or respond to calcium fluctuations accurately. In research, fluorescent calcium sensors are used to visualize Ca²⁺ changes in cells, helping us understand biological processes and disease mechanisms more clearly.
