Two‐pore channels (TPCs) constitute a small family of cation channels expressed in endo‐lysosomal compartments. TPCs have been characterized as critical elements controlling Ca2+‐mediated vesicular membrane fusion and thereby regulating endo‐lysosomal vesicle trafficking. Exo‐ and endocytotic trafficking and lysosomal degradation are major mechanisms of adaption of epithelial transport. A prime example of highly regulated epithelial transport is the tubular system of the kidney. We therefore studied the localization of TPC protein 1 (TPC1) in the kidney and its functional role in the dynamic regulation of tubular transport.
