However, the signal transduction pathways that lead to plant cell responses are poorly understood. More than 30 genes encoding CDPKs have been identified in the model plant, Arabidopsis thaliana.
Calcium binding to the calmodulin-like domain activates the enzyme in vitro and presumably in vivo.
However, the role of specific CDPKs in plant cells is still largely unknown. The long-term goal of the research in the Hrabak laboratory is to understand the role of CDPKs in plants, especially their predicted involvement in signal transduction pathways.
