MGI Phenotype FUNCTION: The protein encoded by this gene is a cysteine protease inhibitor involved in neurodegenerative and cardiovascular processes. The encoded protein inhibits aggregation of beta-amyloid protein, a hallmark of Alzheimer's disease, so it may be useful as a therapeutic. This protein also may be a biomarker for atherosclerosis.

PHENOTYPE: Mice homozygous for a null allele exhibit increased metastatic potential and decreased susceptibility to ischemic brain injury. [provided by MGI curators]
