A mitotic cdk-cyclin complex triggers entry into mitosis.
<span>
Cdk-cyclin complex consists of two units: cdk which is a cyclin-dependent kinase (catalytic subunit) and cyclin (regulatory subunit). This complex play a crucial role in cell cycle progression. There are different types of cdk-cyclin complex, for example, Cdk1-cyclin B1 complex triggers entry into mitosis (progresses the cell cycle through G2/M mitotic phase).</span>
