Abstract:Aquaporin‐2 (AQP2) is a homotetrameric water channel responsible for the final water reuptake in the kidney. Disease‐causing AQP2 mutations induce nephrogenic diabetes insipidus (NDI), a condition that challenges the bodily water balance by producing large urinary volumes. In this study, we characterize three new AQP2 mutations identified in our lab from NDI patients (A120D, A130V, T179N) along the previously reported A47V variant. Using Xenopus oocytes, we compared the key functional and biochemical features … Show more
