The fоllоwing diаgrаm shоws signаling via the Wnt ligand and Fzd/LRP receptor. On the left, the ligand is absent, and on the right, the ligand has activated the receptor complex. Beta catenin is a transcription factor whose activity promotes cell growth (amongst many other things.) A. Using this diagram, list one protein that works as a tumor suppressor and one protein that is functioning as a proto-oncogene in this pathway. B. Beta catenin protein is a special case and it can also bind to E-cadherin and actin in cells. When beta catenin is bound to these alternate proteins, what type of function does this complex serve in cells? (If you don't recall the exact name that's ok, just describe it.)
