Distinct pathways for the involvement of WNK4 in the signaling of hypertonicity and EGF.

WNK4 kinase mutations produce the autosomal dominant disorder familial hyperkalemia and hypertension (FHH), also known as pseudohypoaldosteronism type II, by a molecular mechanism that is not completely understood. In vitro experiments in frog oocytes showed that WNK4 affects ion transport systems such as the Na-Cl cotransporter and the renal outer… CONTINUE READING
