Phosphorylation-dependent subfunctionalization of the calcium-dependent protein kinase CPK28.

Calcium (Ca)-dependent protein kinases (CDPKs or CPKs) are a unique family of Ca sensor/kinase-effector proteins with diverse functions in plants. In , CPK28 contributes to immune homeostasis by promoting degradation of the key immune signaling receptor-like cytoplasmic kinase BOTRYTIS-INDUCED KINASE 1 (BIK1) and additionally functions in vegetative-to-reproductive stage transition. How CPK28 controls these seemingly disparate pathways is unknown.
