    Alomone Labs rabbit anti aqp2 antibody
    Mass spectrometry analysis of synthetic peptides corresponding to the COOH-terminal tail of human <t>AQP2</t> did not detect any significant phosphorylation of the water channel by AMPK. Protease-treated peptides (trypsin or LysC) or full-length peptides are indicated with bold underlined amino acids, indicating where phosphorylation was detected. The no. in parentheses indicates the adjusted spectral count of that particular phosphorylation site. The adjusted spectral count is obtained by multiplying the spectral count of each site with its phosphorylated probability reported by PhosphoRS. The last column indicates the percent sequence coverage. SAMS peptide was used as a positive control.

Polarized mpkCCD c14 cells were treated with vehicle (DMSO) or the AMPK activator AICAR (1 mM) for 4 h and then 10 μM forskolin (vs. vehicle) for the last 2 h before cell harvesting. 5% of the cell lysates were used for immunoblotting using antibodies against AQP2 or actin as a loading control.

    AMPK activator AICAR induces intracellular redistribution of AQP2 in ex vivo kidney slices. A : confocal images of AQP2 immunofluorescence labeling (green) in kidney slices incubated in Ringer buffer alone for 75 min display an apical distribution of the water channel. Asterisks indicate the position of the lumen of the collecting ducts. B : addition of 1 mM AICAR for 75 min induced a cytosolic distribution of AQP2. C : incubation of kidney slices with dDAVP for the last 15 min of a 75-min incubation revealed apical accumulation of AQP2. D : however, preincubation of slices with AICAR did not prevent the dDAVP-induced apical accumulation of AQP2. E : regions of interest (ROIs; example shown in A ). Quantification of the mean (±SE) AQP2-associated mean pixel intensity (MPI) of apical-to-cytoplasmic ratio [arbitrary units (AU)] relative to that of cells measured under the control condition was used as a measure of apical AQP2 accumulation. Additional incubations of kidney slices in Ringer buffer were performed in the absence ( F ) or presence ( G ) of the PKA inhibitor myristoylated protein kinase inhibitor (mPKI; 10 μM) for 75 min. H : the relative AQP2 mean pixel intensity apical-to-cytoplasmic ratio was reduced dramatically with mPKI treatment. Data were obtained from at least 3 separate kidney slice experiments, using kidneys from at least 3 animals, and measuring a total of at least 30 cells per condition. * P

    AMPK inhibition promotes AQP2-mediated oocyte swelling and shortens time to lysis. Oocytes were microinjected with cRNAs for AQP2 and the different indicated AMPK constructs [WT-AMPK-α (●), dominant-negative (DN) AMPK-α1-K45R (■), and constitutively active (CA) AMPK-γ1-R70Q (▲)]. After 3 days, the oocytes were subjected to hypotonic shock in deionized water. Oocyte times to lysis were assessed by microscopy, and the mean times to lysis (normalized to that of the WT-AMPK-expressing group for each batch) are shown for all of the data obtained for these 3 groups. Oocytes expressing DN-AMPK had a significantly reduced time to lysis relative to each of the other two groups. * P

    AMPK fails to significantly phosphorylate AQP2 in vitro. V5-tagged AQP2 was expressed in HEK-293 cells, immunoprecipitated, and incubated with [γ- 32 P]ATP in the presence of PKA catalytic subunit (positive control) or in the presence or absence of AMPK holoenzyme. A phosphoscreen image ( top ) and immunoblot ( bottom ) of the same membrane are shown (representative of 4 experiments). AQP2 gets robustly phosphorylated in the presence of PKA, but only weakly phosphorylated in the presence of AMPK ( top ). PKA catalytic subunit and the AMPK β-subunit get autophosphorylated, as indicated. The immunoblot ( bottom ) reveals similar AQP2 loading in all lanes.

    Figure Lengend Snippet: AQP2 expression and localization in Epac1 −/− and Epac2 −/− mice. A ) Representative Western blots from whole kidney lysates of Epac WT, Epac1 −/− , and Epac2 −/− mice probed with anti-AQP2 antibodies. AQP2 is present as upper duplet of glycosylated bands around 37 kDa and lower nonglycosylated band at 29 kDa. B ) Summary graph comparing total renal AQP2 expression (both glycosylated and nonglycosylated forms) in Epac WT, Epac1 −/− , and Epac2 −/− mice from Western blots similar to that shown in A ). * P

    Article Snippet: We used the primary antibodies against anti-AQP2 (1:1000, AQP2-002; Alomone Labs, Jerusalem, Israel), anti–Na+ -K+ -Cl− cotransporter type 2 ( SLC12A1 ; NKCC2; rabbit polyclonal, 1:1000, ANT-072; Alomone Labs), anti–NHE-3, pS552 NHE-3 (mouse monoclonal, 1:100, sc-136368, sc-53962; Santa Cruz Biotechnology, Dallas, TX, USA), anti-Na+ /H+ exchanger regulatory factor isoform 1 (NHERF1; mouse monoclonal, 1:1000, sc-271552; Santa Cruz Biotechnology), anti-pT96 T101 NKCC2 (rabbit polyclonal, 1:2000, gift of B. Forbush, Yale University, New Haven, CT, USA), anti-pT53 thiazide-sensitive Na+ -Cl− cotransporter ( SLC12A3 ) (NCC; rabbit polyclonal, 1:1000; p1311-53; PhosphoSolutions, Aurora, CO, USA), anti–α subunit of epithelial Na+ ).
