Gene: AQP4 (aquaporin 4) Homo sapiens
Symbol: AQP4
Name: aquaporin 4
Description: Exhibits identical protein binding activity and water channel activity. Involved in several processes, including cellular response to interferon-gamma; multicellular organismal water homeostasis; and protein homotetramerization. Localizes to several cellular components, including external side of plasma membrane; integral component of plasma membrane; and sarcolemma. Implicated in Meniere's disease; blindness; neuromyelitis optica; optic neuritis; and temporal lobe epilepsy. Biomarker of Meniere's disease; cerebral amyloid angiopathy; mitochondrial DNA depletion syndrome 4a; neurodegenerative disease (multiple); and thymoma.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: AQP-4; aquaporin 4 isoform delta4; aquaporin type4; aquaporin-4; HMIWC2; mercurial-insensitive water channel; MGC22454; MIWC; WCH4
