The accurate transmission of genetic information from a cell to a daughter cell is ensured by the tight regulation of the four stages of the cell cycle. The stages of this cycle include: Gap 1 (G1) phase, DNA synthesis (S) phase, gap 2 (G2) phase, and mitosis (M) phase. For each phase, there is a corresponding group … See more Cyclins were discovered by Timothy Hunt, Leland H.

WebE-type cyclins (cyclin E1 and cyclin E2) are expressed during the late G1 phase of the cell cycle until the end of the S-phase. The activity of cyclin E is limiting for the passage of cells through the restriction point "R" which marks a "point of no return" for cells entering the division cycle from a resting state or passing from G1 into S-phase.

WebIt encodes a cell cycle inhibitor that binds to G1 cyclin-CDK complexes. Thus p57KIP2 causes arrest of the cell cycle in G1 phase.
