AQP9 (Aquaporin 9) is a Protein Coding gene. Diseases associated with AQP9 include Infective Endocarditis and Endocarditis. Among its related pathways are Aquaporin-mediated transport and Nanog in Mammalian ESC Pluripotency. AQP9 encodes a member of a subset of aquaporins called the aquaglyceroporins.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.
