Which of the following is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?

Cyclin is a protein synthesized at specific times during the cell cycle that associates with a kinase (CDK) to form a catalytically active complex. Cyclin-CDK complexes regulate the progression of the cell cycle by phosphorylating various target proteins.


Which cyclin forms the primary Cdkc that controls the G2 stage?

Cyclin B forms the primary Cyclin-dependent kinase complex (Cdkc) that controls the G2 stage of the cell cycle. Cyclin B-Cdk complex plays a crucial role in regulating the progression from the G2 phase to mitosis by phosphorylating specific target proteins.


What causes the decrease in the amount of cyclin at a specific point in the cell cycle?

The decrease in cyclin levels at a specific point in the cell cycle is typically caused by the cyclin being targeted for degradation by ubiquitin-mediated proteolysis. This process is regulated by the activity of specific enzymes called ubiquitin ligases, which mark the cyclin for destruction by the proteasome. This decrease in cyclin levels is important for progression to the next phase of the cell cycle.


What is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?

Cyclins are proteins that are synthesized at specific times during the cell cycle and associate with cyclin-dependent kinases (CDKs) to form a catalytically active complex. This complex regulates the progression of the cell cycle by phosphorylating specific target proteins.


What causes the MPF complex to initiate mitosis in the cell cycle?

The MPF complex is activated by the phosphorylation of its Cyclin B subunit by Cyclin-dependent kinase (Cdk), causing the complex to become active and initiate mitosis. This phosphorylation is regulated by various factors such as growth factors, DNA damage, and regulatory proteins within the cell cycle.

What is M-cyclin?

M-cyclin is a type of cyclin protein that is involved in regulating the cell cycle. It works in conjunction with cyclin-dependent kinases to drive the progression of cells through different phases of the cell cycle. M-cyclin specifically plays a key role in controlling the transition from G2 phase to mitosis.

Would a growth factor increase or decrease cyclin levels?

A growth factor would increase cyclin levels. Growth factors signal a cell to enter the cell cycle, which involves an increase in cyclin levels to regulate cell division.
