Effects of renal ischemia–reperfusion injury on occludin and acid–base transporter proteins. Intercalated cell-specific delocalization of occludin may cause the polarity loss or partial internalization of H+-ATPase, Rhcg, and AE1. Abnormal occludin distribution may also lead to backleak (curved arrows) of secreted ions through the paracellular pathways
