Global cleavage of cellular proteins by activated caspases is a hallmark of apoptosis, which causes biochemical collapse of the cell. Recent studies suggest that, rather than completely destroying a protein, caspase cleavage can confer novel characteristics or functions. In this respect, the post-caspase role of Bcl-2 family proteins remains uncharacterized. Here, we showed that Mcl-1, a pro-survival member of the Bcl-2 family, was cleaved by caspase-3 in non-small cell lung cancer (NSCLC) cells undergoing chemotherapeutic agent-triggered apoptosis. Caspase cleavage partially impaired the anti-apoptotic activity of Mcl-1 by reducing its mitochondrial localization and impeding its association with ... More
