|
When does the Cyclin regulator function? |
Produced in response to internal/external triggers. |
|
When does the Cdk regulator function? |
When it binds to a cyclin |
|
When does the Rb regulator function? |
Primarily G1 checkpoint |
|
When does the p53 regulator function? |
Primarily G1 checkpoint; acts when DNA damage is detected. |
|
When does the p21 regulator function? |
Primarily G1 checkpoint |
|
When does the E2F regulator function? |
Primarily G1 checkpoint; in the transition from G1 to S |
|
What does the Cyclin regulator do? |
Binds to Cdks; helps to activate the Cdk/cyclin complex |
|
What does the Cdk regulator do? |
Phosphorylate other proteins, causing the cell cycle to advance |
|
What does the Rb regulator do? |
Monitors cell size; binds and inhibits transcription factors (such as E2F) |
|
What does the p53 regulator do? |
Stops the cell cycle and recruits DNA repair enzumes; can trigger apoptosis; triggers production of p21 |
|
What does the p21 regulator do? |
Enforces a p53-induced cell cycle stop; inhibits Cdk/cyclin complexes |
|
What does the E2F regulator do? |
Transcription factor that activates/promotes production of specific proteins. |
