Caspase-2 has been shown to function in apoptosis and in some non-apoptotic pathways, including tumor suppression and aging. Caspase-2 has some unique features and is the only caspase that constitutively localizes to the nucleus, although its nuclear function remains unknown. During apoptosis signaling, caspase-2 rapidly homodimerizes, which leads to its activation and proteolytic processing. The activation of caspase-2 can be measured by assessing its dimerization and/or cleavage of the caspase-2 zymogen and its substrates. This chapter outlines commonly used methods to purify recombinant caspase-2 and assess its activity and function in vitro and in cultured cells or tissue extracts.
