Biological Activity
In Arabidopsis, protein phosphatase 2C (PP2C) negatively regulates plant hormone, abscisic acid (ABA) signal transduction. In eukaryotes, this protein modulates the cell cycle by reversing the activating phosphorylation of cyclin-dependent protein kinases (CDKs). PP2C acts as a crucial physiological regulators of cell growth and of cellular stress signaling.
