These mice express a human aminopeptidase puromycin sensitive (hPSA or NPEPPS) gene directed by its endogenous promoter/enhancer regions on a BAC transgene. Mice hemizygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. PSA is a cytosolic aminopeptidase that hydrolyzes N-terminal amino acids. PSA is considered to have neuroprotective qualities due to its ability to degrade certain proteins associated with neurodegenerative diseases (TAU and polyglutamine expansion repeat-containing proteins). hPSA overexpression is seen in the cerebral cortex, spinal cord, cerebellum, hippocampus, and brain stem at a 2-3 fold greater level than endogenous PSA. hPSA activity is also increased in muscle, kidney, and liver. These mice may be useful for studying PSA protection in neurodegenerative disorders.
