CPPS FINAL EXAM Practice Questions WITH CORRECT ANSWERS Graded A+ | 2023/2024. What is the importance of RBD in Raf activation? - Correct Answer-It is the N-terminal regulatory domain of the Raf protein. The RBD needs to interact with RasGTP to enable activaiton of Raf. Interaction of RBD with RasGTP at the membrane destabilizes Raf interaction with 14-3-3. This allows for PP2A to dephosphorylate Raf phosphoserines (the locks on the inactive state). What is RBD? - Correct Answer-Ras Binding...
