N-glycosylation of the Xenopus laevis ClC-5 protein plays a role in cell surface expression, affecting transport activity at the plasma membrane.

Abstract excerpt

Mutations in the gene encoding ClC-5 lead to X-linked hypercalciuric nephrolithiasis (XLHN), characterized by proteinuria, hypercalciuria, and phosphaturia. In renal proximal tubule cells, ClC-5 was identified as an important player in endocytosis, which ensures reabsorption of filtered protein. However, the recent finding that ClC-5 is a Cl(-)/H(+) antiporter and not a Cl(-) channel as long thought points to the...
