This project aims to provide a mechanistic and dynamic picture of the structure, function and physiology of the human calcium sensing receptor (CaSR), which is critical for vertebrate life. By responding to chemicals in the body, it acts as a universal nutrient sensor to maintain extracellular calcium homeostasis and mediate biological functions, including neurotransmission, inflammation, digestion, blood pressure and development. However, it is not known how this single receptor controls the actions of multiple ligands to mediate numerous functions. By elucidating the roles of the CaSR and its ligands, this project aims to better understand fundamental physiological processes.Read moreRead less
