Novel Calcium/Calmodulin-modulated Proteins
Ca2+/CaM-regulated protein phosphorylation is believed to play a pivotal role in amplifying and diversifying the action of Ca2+-mediated signals (Poovaiah and Reddy 1993). Although Ca2+/CaM-dependent protein phosphorylation is implicated in regulating a number of cellular processes in plants, not much is known about Ca2+/CaM-dependent protein kinases and their role in Ca2+ signaling. A chimeric Ca2+/CaM-dependent protein kinase (CCaMK) gene with a neural visinin-like Ca2+-binding domain was cloned and characterized (Patil et al 1995). CCaMK is characterized by the presence of a catalytic domain, a CaM-binding domain, and a neural visinin-like Ca2+-binding domain in a single polypeptide, making it distinctly different from other protein kinases (Takezawa et al 1996a, Ramachandiran et al 1997, Poovaiah et al 1999)
