Previous GeneCards Identifiers for AQP5 Gene
Aquaporin 5 (AQP5) is a water channel protein. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein (MIP or AQP0). Aquaporin 5 plays a role in the generation of saliva, tears and pulmonary secretions. AQP0, AQP2, AQP5, and AQP6 are closely related and all map to 12q13. [provided by RefSeq, Jul 2008]
GeneCards Summary for AQP5 Gene
AQP5 (Aquaporin 5) is a Protein Coding gene. Diseases associated with AQP5 include Palmoplantar Keratoderma, Bothnian Type and Diffuse Palmoplantar Keratoderma, Bothnian Type. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Aquaporin-mediated transport. Gene Ontology (GO) annotations related to this gene include transporter activity and glycerol channel activity. An important paralog of this gene is AQP2.
UniProtKB/Swiss-Prot Summary for AQP5 Gene
Forms a water-specific channel (PubMed:8621489, PubMed:18768791). Plays an important role in fluid secretion in salivary glands (By similarity). Required for TRPV4 activation by hypotonicity. Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells (PubMed:16571723). Seems to play a redundant role in water transport in the eye, lung and in sweat glands (By similarity).
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.
