Background Information

HTRA2(High temperature requirement protein A2) is also named as OMI, PRSS25 and belongs to the peptidase S1B family. HTRA2 normally exists in the mitochondria, can cause MMP3 activation in the cytosol under a cell stress condition, which can ultimately lead to demise of dopaminergic neuronal cells(PMID: 22265821). It inhibits mitochondrial superoxide generation, stabilizes mitochondrial membrane potential, and prevents apoptosis at baseline and in response to extracellular inducers of mitochondrial stress(PMID: 18772386). This protein has 4 isoforms produced by alternative splicing.
