Previous GeneCards Identifiers for AQP9 Gene
The aquaporins are a family of water-selective membrane channels. This gene encodes a member of a subset of aquaporins called the aquaglyceroporins. This protein allows passage of a broad range of noncharged solutes and also stimulates urea transport and osmotic water permeability. This protein may also facilitate the uptake of glycerol in hepatic tissue . The encoded protein may also play a role in specialized leukocyte functions such as immunological response and bactericidal activity. Alternate splicing results in multiple transcript variants.

GeneCards Summary for AQP9 Gene
AQP9 (Aquaporin 9) is a Protein Coding gene. Diseases associated with AQP9 include Endocarditis and Hydrarthrosis. Among its related pathways are Aquaporin-mediated transport and Bile secretion. Gene Ontology (GO) annotations related to this gene include transporter activity and glycerol channel activity. An important paralog of this gene is AQP3.
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.
