General description

Aquaporin-4 (AQP-4) is also known as Mercurial-insensitive water channel. AQP-4 is an osmoreceptor which regulates body water balance and mediates water flow within the central nervous system. It is expressed predominantly in the mature brain, but also in the eye, kidney, intestine and lung. AQP-4 is a multi-pass membrane protein that is part of a complex along with MLC1, TRPV4, HEPACAM and ATP1B1.

Specificity

This antibody recognizes the cytoplasmic domain of Aquaporin-4.

Immunogen

Epitope: Cytoplasmic domain
KLH-conjugated linear peptide corresponding to the cytoplasmic domain of rat Aquaporin-4.

Application

Anti-Aquaporin-4 is an antibody targeting the Aquaporin-4 protein, validated for use in WB.

Maintenance of glutamate and water homeostasis in the brain is crucial to healthy brain activity. Astrocytic glutamate transporter-1 (GLT1) and aquaporin-4 (AQP4) are the main regulators of extracellular glutamate and osmolarity, respectively. Several studies have reported colocalization of GLT1 and

Astrocytes regulate extracellular glutamate and water homeostasis through the astrocyte-specific membrane proteins glutamate transporter-1 (GLT1) and aquaporin-4 (AQP4), respectively. The role of astrocytes and the regulation of GLT1 and AQP4 in epilepsy are not fully understood. In this study, we
