calcium/calmodulin-dependent protein kinase activity diacylglycerol-dependent, calcium-independent serine/threonine kinase activity obsolete calcium-dependent protein kinase activity https://github.com/geneontology/go-ontology/issues/25457 true This term was obsoleted because it is an unnecessary grouping class. All calcium-dependent protein kinases are serine/threonine protein kinases. OBSOLETE. Calcium-dependent catalysis of the reaction: a protein + ATP = a phosphoprotein + ADP. molecular_function GO:0010857
