Target Information

Target General Infomation
Target ID
T15610
Former ID
TTDC00249
Target Name
Puromycin-sensitive aminopeptidase
Gene Name
NPEPPS
Synonyms
PSA; NPEPPS
Target Type
Clinical Trial
Disease Acute myeloid leukemia [ICD9: 205; ICD10: C92.0]
Function
Aminopeptidase with broad substrate specificity for several peptides. Involved in proteolytic events essential for cell growth and viability. May act as regulator of neuropeptide activity. Plays a role in the antigen-processing pathway for MHC class I molecules. Involved in the N-terminal trimming of cytotoxic T-cell epitope precursors. Digests the poly-Q peptides found in many cellular proteins. Digests tau from normal brain moreefficiently than tau from Alzheimer disease brain.
