Schematic of full-length and deletion GFP-APC constructs used in this study (not to scale). Panel A. Full-length GFP-APC including known APC domains. Panel B. pEGFP-APCΔC construct lacking the last 54 amino acids of APC. Panel C. pEGFP-APCΔN+ΔC construct lacking the first 206 and last 54 amino acids of APC. Panel D. pEGFP-APC-C construct consisting of the last 170 amino acids of APC. Panel E. pEGFP-APC-N consisting of the first 746 amino acids of APC.
