Function

Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Plays an essential role in renal water homeostasis. Could also be permeable to glycerol.

Biological Context

Subcellular Location: Apical cell membrane (Multi-pass membrane protein); Basolateral cell membrane (Multi-pass membrane protein); Cell membrane (Multi-pass membrane protein); Cytoplasmic vesicle membrane (Multi-pass membrane protein); Golgi apparatus, trans-Golgi network membrane (Multi-pass membrane protein)
Tissue Specificity: Expressed in collecting tubules in kidney medulla (at protein level). Detected in kidney
Disease Association: Diabetes insipidus, nephrogenic, 2, autosomal (NDI2) : A disorder caused by the inability of the renal collecting ducts to absorb water in response to arginine vasopressin. Characterized by excessive water drinking (polydipsia), excessive urine excretion (polyuria), persistent hypotonic urine, and hypokalemia. Inheritance can be autosomal dominant or recessive. [The disease is caused by variants affecting the gene represented in this entry]
