- Methylation of a Phosphatase Specifies Dephosphorylation and Degradation of Activated Brassinosteroid Receptors
The abundance of brassinosteroid receptors and thus the intensity of brassinosteroid signaling are set by methylation of a protein phosphatase.
- A Peptide-Based Target Screen Implicates the Protein Kinase CK2 in the Global Regulation of Caspase Signaling
Phosphorylation of caspase substrates by the protein kinase CK2 may underlie its role in tumorigenesis.
Protein phosphatase 2A acts as both a positive and negative regulator of brassinosteroid signaling, depending on where in the pathway the phosphatase acts.
