What is the name of the proteins that regulate the cell cycle?

Answer 1

protein kinase are the protiens that regulate cell cycle.

it has 2 subunits-

a)catalytic unit called as cyclin dependent protien kinase (CDK)

b) regulatory subunit called as cyclin binding unit

Answer 2

Yes, cyclins along with cyclin-dependent kinases (Cdks) regulate the cell cycle, especially at G2 checkpoint. The activity of the kinases depends on the fluctuating concentration of the cyclins. At the G2 checkpoint, the Cdk complex called the maturation-promoting factor (MPF) triggers the cell's passage from the G2 checkpoint into the M phase. When the cyclin concentration increases during G2, the cyclin-dependent kinases combine with the cyclins, forming MPF molecules. These MPF molecules then initiate mitosis by phosphorylating a variety of proteins including proteins of the nuclear lamina, promoting fragmentation of the nuclear lamina and the nuclear envelope; MPF is the most active during metaphase. MPF may also contribute to chromosome condensation and spindle formation. But like many regulatory systems, the MPF also has an "off switch." During anaphase, the MPF initiates the degradation of its own cyclin, terminating the M phase. The cell then enters the G1 phase. Many regulatory processes are reversible and cyclins, and Cdks are no exception as the Cdk part of the MPF is recycled and remains in the cell in its inactive form until new cyclin molecules are synthesized during the next round of the cycle in the S and G2 phases.

Answer 3

well since i guess you are asking if cyclins regulate the cell cycle well yes they do.

Answer 4

cyclins
