function:Specialized low-affinity vasopressin-regulated urea transporter. Mediates rapid transepithelial urea transport across the inner medullary collecting duct and plays a major role in the urinary concentrating mechanism.,induction:Isoform 1 is induced by low protein in the diet, isoform 2 by dehydration.,similarity:Belongs to the urea transporter family.,subunit:Isoform 1 interacts with SNAPIN which may be important for recruitment to the plasma membrane.,tissue specificity:Isoform 1 and isoform 2 are expressed in the inner medulla of the kidney.,
Apical cell membrane; Multi-pass membrane protein.
Isoform 1 and isoform 2 are expressed in the inner medulla of the kidney.
