How might mutations in the APC gene that lead to mis-folded APC protein result in a change of Beta-catenin signaling levels?

a) APC is a transcription factor that binds and regulates the Beta-catenin promoter b) Mis-folded APC will most likely result in lower levels of intact Beta-catenin in the cell c) Mis-folded APC may prevent assembly of the protein complex that degrades Beta-catenin d) Mis-folded APC will prevent Wnt signals from binding the frizzled receptor, and elevated Beta-catenin signaling will result
