摘要

CIC-7, α chloride-proton exchanger on late endo-somes and lysosomes, is proposed to play a role in vesicular acidification by providing the electrical shunt for the electrogenic proton translocation via V-type H~+-ATPases. Using co-immunoprecipitation, we identified the lysosomal transmembrane protein Ostm 1 as a novel beta-subunit of ClC-7, which is required for protein stability, thereby promoting proper function of the exchanger. Loss of ClC-7 was found to cause osteopetrosis and lysosomal storage disease in humans and mice. However, the causative mechanism for lysosomal dysfunction under loss of ClC-7 remained unknown. Following the intravenous injection of protein in mice in-vivo pulse chase experiments demonstrated that the lysosomal storage disease caused by ClC-7 depletion is due to slower protein degradation.
