Product Overview
This rabbit polyclonal antibody detects protein phosphatase 1F (gene PPM1F) in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 49.8 kDa, and the supplier reports an observed band at about 50 kDa.
Protein phosphatase 1F (PPM1F, also called POPX2 or CaMKP) is a PP2C-family serine/threonine phosphatase. It dephosphorylates and inactivates CaMKII, CaMKI and CaMKIV and can promote apoptosis. It has also been linked to cell motility and is studied in calcium signaling.
