Caspase-2 is a highly conserved member of the caspase family involved in the initiation and execution of apoptosis. While its function is still poorly understood, caspase-2 is thought to be important for apoptosis in response to DNA damage, bacterial infection, or abnormal mitosis (1). Caspase-2 contains an N-terminal caspase recruitment domain, the large p19 subunit containing the active site, and the small C-terminal p12 subunit (1). In response to various apoptotic signals caspase-2 undergoes dimerization.
