cyclin-dependent protein serine/threonine kinase activity

Details: 
Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. This reaction requires the binding of a regulatory cyclin subunit and full activity requires stimulatory phosphorylation by a CDK-activating kinase (CAK). [GOC:pr, GOC:rn, PMID:7877684, PMID:9841670]
