A Non-Radioactive Method for Measuring PP2A Activity in Plants
Authors:  Jian Chen, Guoxin Shen and Hong Zhang, date: 09/05/2015, view: 2076, Q&A: 0
Protein phosphatase 2A (PP2A) is a group of important cellular regulators in eukaryotes that dephosphorylate more than 30% of cellular proteins whose activities are turned on or off by phosphorylation. In plants, PP2A was found to regulate critical ...
