Protein kinases with calmodulin-like domains: novel targets of calcium signals in plants.
Recently, a novel calcium-dependent protein kinase has been identified that is structurally distinguished by the localization of a calcium-binding regulatory domain fused to a serine/threonine catalytic domain. The regulatory domain is homologous to calmodulin and contains four helix-loop-helix calcium-binding sites. As a result, the kinase is directly activated by calcium without a requirement for other effector molecules.
