CC -!- FUNCTION: Forms a water-specific channel (PubMed:19383790, CC PubMed:7559426, PubMed:8601457). Plays an important role in brain water CC homeostasis (PubMed:37143309). It is involved in glymphatic solute CC transport and is required for a normal rate of water exchange across CC the blood brain interface. Required for normal levels of cerebrospinal CC fluid influx into the brain cortex and parenchyma along paravascular CC spaces that surround penetrating arteries, and for normal drainage of CC interstitial fluid along paravenous drainage pathways. Thereby, it is CC required for normal clearance of solutes from the brain interstitial CC fluid, including soluble beta-amyloid peptides derived from APP. Plays CC a redundant role in urinary water homeostasis and urinary concentrating CC ability (By similarity). {ECO:0000250|UniProtKB:P55088, CC ECO:0000269|PubMed:19383790, ECO:0000269|PubMed:37143309, CC ECO:0000269|PubMed:7559426, ECO:0000269|PubMed:8601457}.

The tetramers can form CC oligomeric arrays in membranes. The size of the oligomers differs CC between tissues and is smaller in skeletal muscle than in brain. CC Interaction between AQP4 oligomeric arrays in close-by cells can CC contribute to cell-cell adhesion (By similarity). Part of a complex CC containing MLC1, TRPV4, HEPACAM and ATP1B1 (PubMed:22328087). CC {ECO:0000250|UniProtKB:P47863, ECO:0000269|PubMed:19383790, CC ECO:0000269|PubMed:22328087}.
