In heterologous expression systems, interaction of the E3 ubiquitin ligasesWWP2and Nedd4-2 with a &quot;PY-motif&quot; in the cytoplasmic C terminus of ClC-5 stimulates its internalization from the plasma membrane and may influence receptor-mediated endocytosis. We asked whether this interaction is relevant in vivo and generated mice in which the PY-motif was destroyed by a point mutation. Unlike ClC-5 knock-out mice, these knock-in mice displayed neither low molecular weight proteinuria nor hyperphosphaturia, and both receptor-mediated and fluid-phase endocytosis were normal. The abundances and localizations of the endocytic receptor megalin and of the Na+-coupled phosphate transporter NaPi-2a (Npt2) were not changed, either. To explore whether the discrepancy in results from heterologous expression studies might be due to heteromerization of ClC-5 with ClC-3 or ClC-4 in vivo, we studied knock-in mice additionally deleted for those related transporters. Disruption of neither ClC-3 nor ClC-4 led to proteinuria or impaired proximal tubular endocytosis by itself, nor in combination with the PY-mutant of ClC-5. Endocytosis of cells lacking ClC-5 was not impaired further when ClC-3 or ClC-4 was additionally deleted. We conclude that ClC-5 is unique among CLC proteins in being crucial for proximal tubular endocytosis and that PY-motif-dependent ubiquitylation of ClC-5 is dispensable for this role.","lang":"eng"}],"doi":"10.1074/jbc.M110.115600","author":[{"first_name":"Gesa","full_name":"Rickheit, Gesa","last_name":"Rickheit"},{"last_name":"Wartosch","full_name":"Wartosch, Lena","first_name":"Lena"},{"full_name":"Schaffer, Sven","first_name":"Sven","last_name":"Schaffer"},{"full_name":"Stobrawa, Sandra M","first_name":"Sandra","last_name":"Stobrawa"},{"orcid":"0000-0002-7673-7178","first_name":"Gaia","full_name":"Gaia Novarino","id":"3E57A680-F248-11E8-B48F-1D18A9856A87","last_name":"Novarino"},{"last_name":"Weinert","first_name":"Stefanie","full_name":"Weinert, Stefanie"},{"full_name":"Jentsch, Thomas J","first_name":"Thomas","last_name":"Jentsch"}],"_id":"2311","title":"Role of ClC-5 in renal endocytosis is unique among ClC exchangers and does not require PY-motif-dependent ubiquitylation","quality_controlled":0,"intvolume":"       285","volume":285,"date_updated":"2021-01-12T06:56:42Z","publist_id":"4618","type":"journal_article","extern":1}
