New cards

What is translational control?

Switching translation on and off

2
New cards

If we don't want translation to occur, what 2 things could happen?

Degrade mRNA

OR

Inhibitory proteins binding to the mRNA.

3
New cards

What does inhibitory proteins binding to the mRNA do?

Stops the mRNA from binding with the ribosome.

4
New cards

If we want translation to occur, what happens?

Activate initiation factors

New cards

Activate initiation factors

This allows mRNA to bind to the ribosome. This is done by phosphorylation. We add a phosphate group to the proteins to activate them. This is done by protein kinases, and protein kinases can be activated by cAMP.
