The precise regulation of the body's phosphate homeostasis is a critical task. Treatment of hyperphosphatemia, which becomes inevitable in later stages of chronic kidney disease (CKD), is limited to dietary phosphate restriction and oral phosphate binders. Two transport proteins mediate renal phosphate reabsorption, the sodium-phosphate cotransporters Npt2a and Npt2c. The former mediates the majority of renal phosphate reabsorption (70-80%), which is a hormonally regulated process and requires p...
