Summaries for AQP1 Gene

Entrez Gene Summary for AQP1 Gene

  • This gene encodes a small integral membrane protein with six bilayer spanning domains that functions as a water channel protein. This protein permits passive transport of water along an osmotic gradient. This gene is a possible candidate for disorders involving imbalance in ocular fluid movement. [provided by RefSeq, Aug 2016]

GeneCards Summary for AQP1 Gene

AQP1 (Aquaporin 1 (Colton Blood Group)) is a Protein Coding gene. Diseases associated with AQP1 include Central Pontine Myelinolysis and Fibrogenesis Imperfecta Ossium. Among its related pathways are Aquaporin-mediated transport and Erythrocytes take up carbon dioxide and release oxygen. GO annotations related to this gene include transporter activity and potassium channel activity. An important paralog of this gene is ENSG00000250424.

UniProtKB/Swiss-Prot for AQP1 Gene

  • Forms a water-specific channel that provides the plasma membranes of red cells and kidney proximal tubules with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.

Tocris Summary for AQP1 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.
