Urea Transporters Identified as Novel Diuretic Drug Targets

Background: Urea Transporters are a family of membrane channel proteins that facilitate the passive transport of urea across the plasma membrane. UTs are divided into two subgroups, UT-A and UT-B. UT-As are primarily located in renal tubule epithelia and UT-Bs are highly expressed in renal descending vasa recta and extrarenal multiple tissues. Various urea transporter knockout mice exhibit low urine concentrating ability, which suggests that UTs...
