In growing cells there are two classes of proteins that can trigger or check the progression of the cell cycle from the G1 phase to the M phase. These protein classes are Cyclins and CDK (Cyclin Dependant Kinases). Tim Hunt is the English biochemist who discovered cyclins; they are so named because of their significance in initiation and regulating the cell cycle in a cyclic manner.
