Calcium Sensing Receptor (CaSR)
The Calcium Sensing Receptor (CaSR) is a protein found in various tissues, including the parathyroid glands and kidneys. It helps the body maintain the right level of calcium in the blood. When calcium levels are high, CaSR signals the body to reduce calcium release from bones and decrease calcium absorption in the intestines, helping to prevent excess. Conversely, when calcium levels are low, it signals for more calcium to be released. This receptor is crucial for overall health, as calcium is vital for many bodily functions, including muscle contraction and nerve signaling.
