Serine protease HtrA2/Omi and cell death or survival / 中国病理生理杂志

ABSTRACT

The serine protease HtrA2/Omi is released from the mitochondrial intermembrane space following apoptotic stimuli.Once in the cytosol,HtrA2/Omi has been implicated in promoting cell death in caspase-dependent or caspase-independent pathway.On the other hand,HtrA2/Omi can refold and degrade misfolded proteins in the mitochondria during cell stress.
