This article presents and discusses experiments to demonstrate that the carboxy-terminal of APC contains DNA-binding sequences to inhibit DNA replication directly.

•• Qian J, Perchiniak EM, Sun K, Groden J: The mitochondrial protein hTID-1 partners with the caspase-cleaved adenomatous polyposis cell tumor suppressor to facilitate apoptosis. Gastroenterology 2010;138:1418–28. This article presents and discusses experiments to demonstrate that caspase cleavage of APC releases an amino-terminal segment that relocates to the mitochondria and interacts with an hTID-1 isoform to promote apoptosis.

This article presents and discusses experiments to demonstrate that truncated APC interacts with Bcl2 to stabilize Bcl2 at the mitochondria and to promote cell survival.
