MGI Phenotype FUNCTION: This gene encodes a member of the aquaporin family of intrinsic membrane proteins that function as water-selective channels in the plasma membranes of many cells. This protein is the predominant aquaporin found in brain and has an important role in brain water homeostasis. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. A recent study provided evidence for translational readthrough in this gene and expression of an additional C-terminally extended isoform via the use of an alternative in-frame translation termination codon.

PHENOTYPE: Homozygotes for a targeted mutation exhibit decreased urine osmolality associated with reduced water permeability in inner medullary collecting ducts, increased survival rates and reduced brain edema after acute water intoxication and ischemic stroke, aswell as significant hearing impairment.
