Translational Control

mRNA degradation - the more resistant mRNA is to degradation the more protein will be made.Inhibitory proteins - bind to mRNA and stop it binding to the ribosomeInitiation factors - aid the binding of mRNA to ribosomes.Protein Kinases - addition of a phosphate group changes the tertiary structure. Phosphorylation either activates a protein or deactivates it. Protein kinases are often activated by cAMP.
