Caspase-mediated cleavage of APC results in an amino-terminal fragment with an intact armadillo repeat domain.

Abstract excerpt

During the effector phase of apoptosis, caspase activation appears to be responsible for the distinctive structural changes of apoptosis and perhaps for some of the changes in function of the doomed cells. There is therefore interest in identifying caspase substrates and the details of the cleavage events. Here we define precisely the event responsible for generation of a stable 90 kDa fragment from the...
