Protein Kinase A (PKA) helps animals cope with stressful situations. In the "flight or fight" response, muscle becomes primed for action as a result of the activity of PKA. Upon activation by cAMP, PKA alters the activities of target proteins by phopshorylating specific serine or threonine residues. | Protein Kinase A (PKA) helps animals cope with stressful situations. In the "flight or fight" response, muscle becomes primed for action as a result of the activity of PKA. Upon activation by cAMP, PKA alters the activities of target proteins by phopshorylating specific serine or threonine residues. This enzyme also helps regulate glucose levels. When activated by cAMP, PKA simultaneously catalyzes the breakdown of glycogen and inhibits the synthesis of glucose. (? makes sure this is right) | ||
