| Immunogen: |
Synthetic peptide taken within amino acid region 300-323 on rat Aquaporin 4 protein. |
| Tissue Specificity | Detected in skeletal muscle. Detected in stomach, along the glandular base region of the fundic gland (at protein level). Detected in brain, lung and skeletal muscle, and at much lower levels in heart and ovary. |
| Post Translational Modifications | Phosphorylation by PKC at Ser-180 reduces conductance by 50%. Phosphorylation by PKG at Ser-111 in response to glutamate increases conductance by 40%. Isoform 2: Palmitoylated on its N-terminal region. Isoform 1: Not palmitoylated. |
| Function | Forms a water-specific channel. Plays an important role in brain water homeostasis and in glymphatic solute transport. Required for a normal rate of water exchange across the blood brain interface. Required for normal levels of cerebrospinal fluid influx into the brain cortex and parenchyma along paravascular spaces that surround penetrating arteries, and for normal drainage of interstitial fluid along paravenous drainage pathways. Thereby, it is required for normal clearance of solutes from the brain interstitial fluid, including soluble beta-amyloid peptides derived from APP. Plays a redundant role in urinary water homeostasis and urinary concentrating ability. |
