Molecular mechanisms underlying the sensing of extracellular Ca2+ by parathyroid and kidney cells.

Abstract excerpt

Mineral ion homeostasis in mammalian species is maintained by a complex mechanism comprising sensors of the extracellular calcium concentration (Ca2+0) (i.e. parathyroid cells) as well as effectors that modify their translocation of mineral ions into and out of the extracellular fluid (e.g. kidney) in response to calciotropic hormones. Indirect evidence accumulated over the past decade suggested that parathyroid...
