WebSep 4, 2024 · Cyclins and Kinases. The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins.Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK).Kinases are enzymes that catalyze the transfer … WebIn normal cells signalling is very tightly controlled.
