Misfolded vasopressin V2 receptors caused by extracellular point mutations entail congenital nephrogenic diabetes insipidus.

2000

Vasopressin V2 receptor mutants from three different patients with congenital nephrogenic diabetes insipidus phenotypes were investigated after expression in COS cells. The amino acid exchanges within the human V2 receptor are located in the second extracellular loop (T204N, Y205C and V206D). Confocal microscopy showed that all receptor mutants were strongly expressed but mainly located within the cell. Residual binding capacity for the antidiuretic hormone arginine vasopressin (AVP) could only be detected for the T204N mutant and was 10-fold lower than for the wild-type receptor. Stimulation of transfected cells with 1 microM AVP showed that the T204N mutant was able to activate the adenyl…
