Western Blot: Aquaporin-2 [p Ser261] Antibody [NB100-61100] - Rat kidney lysate showing specific immunolabeling of the ~ 29k and 37k glycosylated form of the AQP2 protein phosphorylated at Ser261. Immunolabeling is ...read more
Phosphopeptide corresponding to amino acid residues surrounding the phosphoSer261of rat aquaporin 2.
Specific for ~29k AQP2 protein phosphorylated at Ser261. 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.
Immunohistochemistry as reported in the literature (Hoffert et al., 2007) Dot Blot was reported in scientific literature.
29 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Water is a critical component of all living cells. Interestingly, tissue membranes show a great degree of water permeability. Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water. Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by special protein aquaporins. Aquaporin 0, and Aquaporin 1 have been the foundation of the growing family of aquaporins. The lens specific Aquaporin 0 represents up to 80% of total lens membrane protein. Defects in Aquaporin 0 are a cause of autosomal dominant cataract. The lens opacity mutation is an AA substitution that inhibits targeting of MIP to the cell membrane. Human Aquaporin 0 is a 263 amino acid transmembrane protein belonging to the MIP family. Aquaporin families of proteins are predicted to contain six transmembrane domains. The N and C terminus are predicted to be cytoplasmic. Aquaporin 2 is located in the collecting tubule.
