 Clonality    Polyclonal
 Host    Rabbit
 Species Reactivity    Rat
Section Bar
 Specificity    Specific for the ~29k AQP2 protein phosphorylated at Ser269. Also recognizes the glycosylated form of AQP2 at ~ 37k. Immunolabeling of the AQP2 band is blocked by preadsorption with the phospho-peptide used as antigen but not by the corresponding dephospho-peptide.
 Purity/Purification    Affinity Purified (Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.)
 Form/Format    100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots
Section Bar
 Antigen    Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser269 of rat aquaporin 2.
 Immunogen Information    Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser269 conjugated to KLH
 Immunogen Species    Rat
 Reactivity Assumed Based on 100% Sequence Homology    Bovine, canine, mouse
 Species Reactivity Note    The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine and mouse tissues based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
 Biological Significance    Aquaporin 2 (AQP2) is a hormonally regulated water channel located in the renal collecting duct. Mutations in the AQP2 gene cause hereditary nephrogenic diabetes insipidus in humans (Iolascon et al., 2007). A vasopressin induced cAMP increase results in the phosphorylation of AQP2 at serine-256 and its translocation from the intracellular vesicles to the apical membrane of principal cells (van Balkom et al., 2002). Serine-269 has been recently identified as a vasopressin-mediated phosphorylation site on AQP2 and as such has shown to potentiate plasma membrane retention of AQP2 (Hoffert JD et al., 2008).
Section Bar
 Preparation and Storage    For long term storage -80 degree C is recommended, but shorter term storage at -20 degree C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stock solution are stable for a minimum of 1 year at -20 degree C.

Shipment: Domestic - Blue Ice; International - Blue Ice or Dry Ice.
 Other Notes    Small volumes of anti-AQP2 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

 NCBI Summary for AQP2    water channel protein involved in water reabsorption and vasopressin regulation in kidney collecting duct cells; mutation is linked to nephrogenic diabetes insipidous (NDI) [RGD, Feb 2006]
Section Bar
 UniProt Comments for AQP2    Function: Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.

Subcellular location: Apical cell membrane; Multi-pass membrane protein. Basolateral cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle membrane; Multi-pass membrane protein. Golgi apparatus › trans-Golgi network membrane; Multi-pass membrane protein. Note: Shuttles from vesicles to the apical membrane. Vasopressin-regulated phosphorylation is required for translocation to the apical cell membrane. PLEKHA8/FAPP2 is required to transport AQP2 from the TGN to sites where AQP2 is phosphorylated. Ref.6

Tissue specificity: Expressed in renal collecting tubules.

Domain: Aquaporins contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA).

Post-translational modification: Ser-256 phosphorylation is necessary and sufficient for expression at the apical membrane. Endocytosis is not phosphorylation-dependent

By similarity.

Sequence similarities: Belongs to the MIP/aquaporin (TC 1.A.8) family. [View classification]

Sequence caution: The sequence AAA41478.1 differs from that shown. Reason: Erroneous initiation.
