Ac-Val-Asp-Gln-Gln-Asp-pNA is a colorimetric substrate for Caspase 2. Caspase 2, part of the ICH-1 sub-family, is a cysteine protease with a poorly defined role in apoptosis. It associates with several apoptotic proteins such as death effector filament-forming Ced-4-like apoptosis protein (DEFCAP), RIP-associated Ich-1/Ced-3-homologue protein with a death domain (RAIDD), and apoptosis repressor with caspase recruitment domain (ARC). Caspase 2 can be activated by the PIDDosome formed by the association of PIDD1 and CRADD. Recent work demonstrates that Caspase-2 resides in the mitochondria and is essential for stress-induced apoptosis.

Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
