Activation of 2‐oxoglutarate receptor 1 (OXGR1) by α‐ketoglutarate (αKG) does not detectably stimulate Pendrin‐mediated anion exchange in Xenopus oocytes
Abstract:SLC26A4/Pendrin is the major electroneutral Cl−/HCO3− exchanger of the apical membrane of the Type B intercalated cell (IC) of the connecting segment (CNT) and cortical collecting duct (CCD). Pendrin mediates both base secretion in response to systemic base load and Cl− reabsorption in response to systemic volume depletion, manifested as decreased nephron salt and water delivery to the distal nephron. Pendrin‐mediated Cl−/HCO3− exchange in the apical membrane is upregulated through stimulation of the β‐IC apic… Show more
