Practice: Which of the following statements about protein kinase A (PKA) is false?
Concept #1: cAMP & PKA
Concept #2: Inactivation of cAMP & PKA
Example #1: Order each of the steps in the activation of PKA (by numbering them 1-4 ; first step is already numbered for you) starting after adenylate cyclase activation.
Concept #3: Inactivation of cAMP & PKA
Practice: What is the function of a phosphatase?
Practice: What could be the result of a mutation in the R subunits of cAMP-dependent protein kinase A (PKA) that inhibits formation of the R2C2 protein complex?
Practice: The image below is a schematic representation of PKA activation from epinephrine binding. Based on the provided numbers in the diagram, how many subunits of catalytically active PKA will there be?
