Previous GeneCards Identifiers for AQP9 Gene
The aquaporins are a family of water-selective membrane channels. The protein encoded by this gene allows passage of a wide variety of noncharged solutes. It stimulates urea transport and osmotic water permeability; there are contradicting reports about its role in providing glycerol permeability. The encoded protein may also play a role in specialized leukocyte functions such as immunological response and bactericidal activity. [provided by RefSeq, Jul 2008]
GeneCards Summary for AQP9 Gene
AQP9 (Aquaporin 9) is a Protein Coding gene. Diseases associated with AQP9 include hydrarthrosis and endocarditis. 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 transporter activity and glycerol channel activity. An important paralog of this gene is AQP10.
UniProtKB/Swiss-Prot for AQP9 Gene
Forms a channel with a broad specificity. Mediates passage of a wide variety of non-charged solutes including carbamides, polyols, purines, and pyrimidines in a phloretin- and mercury-sensitive manner, whereas amino acids, cyclic sugars, Na(+), K(+), Cl(-), and deprotonated monocarboxylates are excluded. Also permeable to urea and glycerol.
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.
