How cells use checkpoints at the end of G1 phase, end of G2 phase, and partway through M phase (the spindle checkpoint) to regulate the cell cycle.

Cyclins and cyclin-dependent kinases (CDKs) are proteins that play an important role in regulating the cell cycle. Cyclins bind to and activate CDKs, which promote cell division.

The cell cycle is usually regulated by checkpoints. These are the factors that a cell considers when deciding whether or not to move forward through the cell cycle, and include both …

In this article, we'll look at a few of the most important core cell cycle regulators: proteins called cyclins, enzymes called Cdks, and an enzyme complex called the APC/C.

The cell cycle is tightly regulated by checkpoints between the G1 and S phase, and between the G2 and mitosis. Key proteins, cyclin-dependent kinases and cyclins, control this process. …

Learn about mechanisms of cell cycle regulation and the major cell cycle checkpoints.
