Functional expression of mutations in the human NaCl cotransporter: evidence for impaired routing mechanisms in Gitelman's syndrome

Gitelman's syndrome is an autosomal recessive renal tubular disorder characterized by
hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. This disorder results
from mutations in the thiazide-sensitive NaCl cotransporter (NCC). To elucidate the
functional implications of mutations associated with this disorder, metolazone-sensitive 22
Na+ uptake, subcellular localization, and glycosidase-sensitive glycosylation of human NCC
(hNCC) were determined in Xenopus laevis oocytes expressing FLAG-tagged wild-type or …
