Application Instructions
| Application Suggestion |
|
||||||
|---|---|---|---|---|---|---|---|
| Application Note | Specific for the ~29k AQP2 protein phosphorylated at Ser264 . 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. * The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist. |
Properties

| Gene Symbol | AQP2 |
| Gene Full Name | aquaporin 2 (collecting duct) |
| Background | 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). Recently, serine-264 has been identified as a novel phosphorylation site on AQP2 and shown to be regulated by vasopressin thus implicating this site as important in AQP2 trafficking and subcellular distribution (Fenton RA et al., 2008). |
| Research Area | Metabolism antibody; Signaling Transduction antibody |
| Calculated MW | 29 kDa |
| PTM | Ser-256 phosphorylation is necessary and sufficient for expression at the apical membrane. Endocytosis is not phosphorylation-dependent. |
