ターゲット情報

  • 機能
    Inhibitor of protein-phosphatase 1. This protein may be important in hormonal control of glycogen metabolism. Hormones that elevate intracellular cAMP increase I-1 activity in many tissues. I-1 activation may impose cAMP control over proteins that are not directly phosphorylated by PKA. Following a rise in intracellular calcium, I-1 is inactivated by calcineurin (or PP2B). Does not inhibit type-2 phosphatases.
  • 配列類似性
    Belongs to the protein phosphatase inhibitor 1 family.
  • 翻訳後修飾
    Phosphorylation of Thr-35 is required for activity.

  • Anti-Protein phosphatase inhibitor 1 antibody [EP902Y] (ab40877) at 1/40000 dilution + Rat brain at 10 µg

    Predicted band size : 19 kDa
    Observed band size : 27 kDa (why is the actual band size different from the predicted?)
  • Immunohistochemical analysis of paraffin-embedded human normal brain tissue using ab40877 diluted 1:100.
  • ICC/IF image of ab40877 stained PC12 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab40877, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • Overlay histogram showing SH-SY5Y cells stained with ab40877 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab40877, 1/20 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) ( 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 80% methanol/permeabilized in 0.1% PBS-Tween used under the same conditions.

レビューと Q&A

The peptide used is derived from the general region of 1-25 aa at the N-terminus.

Thank you for your enquiry. We have never directly tested this, but according to sequence alignment, ab40877 will not cross react with darpp32. If you have any other questions, please do not hesitate to contact me.
