Description

Ubiquitin isopeptidase inhibitor I induces caspase activation and apoptosis (IC50 = ~1.7 μM) through a Bcl-2-dependent and apoptosome-independent mitochondrial pathway that selectively inhibits ubiquitin isopeptidase activity (IC50 = ~30 μM). It has also been shown to induce necrosis in apoptosis-resistant DKO cells.
