Extracellular Calcium-Sensing Receptor

**Semantic type:** Amino Acid, Peptide, or Protein|Receptor

**Definition:** Extracellular calcium-sensing receptor (1078 aa, ~121 kDa) is encoded by the human CASR gene. This protein is involved in calcium sensing, G-protein-coupled receptor signaling and the regulation of both parathyroid hormone secretion and renal cation reabsorption.
