The knock-out mouse of this endosomal kidney transporter has a severe endocytic phenotype believed to be due to a defect in vesicular acidification. The current study shows a similarly impaired endocytic phenotype for the uncoupled mutant, but the acidification of endosomes was unaffected.\n            <jats:bold>\n              Weinert\n              <jats:italic>et al.<\/jats:italic>\n            <\/jats:bold>\n            (p.\n            <jats:related-article xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"doi\" page=\"1401\" related-article-type=\"in-this-issue\" vol=\"328\" xlink:href=\"10.1126\/science.1188072\">1401<\/jats:related-article>\n            , published online 29 April) used a similar strategy to investigate the consequence of the equivalent mutation in the lysosomal transporter ClC-7, which is highly expressed in the resorption lacuna of osteoclasts and whose knock-out in mice produces lysosomal storage disease and severe osteopetrosis. A similar (though less severe) phenotype was observed in the knock-in mice containing the uncoupled ClC-7, indicating that coupled transport plays a critical role in lysosomes.\n
