Suppоse yоu аre а drug reseаrcher studying this pathway. Chоose one of the proteins in the signaling pathway, and propose a hypothetical drug (let's call it Drug H) that would reduce proliferation in these cells. Say why you chose this protein to target, and explain briefly: What do you want the drug to do to this protein, in terms of 1) its affinity and 2) its efficacy? 3) How will this drug affect the other proteins in the pathway, and what is the ultimate result on the cell?
