What is translational control?

Switching translation on and off

2
New cards

If we don't want translation to occur, what happens?

Degrade mRNA

OR

Inhibitory proteins binding to the mRNA.

3
New cards

Inhibitory proteins binding to the mRNA

This will stop 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 using protein kinases.

  • Protein kinases can be activated by cAMP.
