MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Aquaporin 8 (AQP8) is a water channel protein. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein (MIP or AQP0). Aquaporin 8 mRNA is found in pancreas and colon but not other tissues. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a disruption in this gene results in enlarged testes and a reduction in water permeability in plasma membrane of testes. [provided by MGI curators]
