Summaries for AQP2 Gene

Entrez Gene Summary for AQP2 Gene

  • This gene encodes a water channel protein located in the kidney collecting tubule. It belongs to the MIP/aquaporin family, some members of which are clustered together on chromosome 12q13. Mutations in this gene have been linked to autosomal dominant and recessive forms of nephrogenic diabetes insipidus. [provided by RefSeq, Oct 2008]

GeneCards Summary for AQP2 Gene

AQP2 (Aquaporin 2 (Collecting Duct)) is a Protein Coding gene. Diseases associated with AQP2 include diabetes insipidus, nephrogenic and hydronephrosis. Among its related pathways are Nanog in Mammalian ESC Pluripotency and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include actin binding and PDZ domain binding. An important paralog of this gene is AQP5.

UniProtKB/Swiss-Prot for AQP2 Gene

  • 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

Tocris Summary for AQP2 Gene

  • Aquaporins (AQPs) are integral membrane proteins that facilitate the transport of water across biological membranes along an osmotic gradient. There have been 13 AQP isoforms (AQP0-AQP12) identified in humans and rodents to date.
