Previous GeneCards Identifiers for NPEPPS Gene
This gene encodes the puromycin-sensitive aminopeptidase, a zinc metallopeptidase which hydrolyzes amino acids from the N-terminus of its substrate. The protein has been localized to both the cytoplasm and to cellular membranes. This enzyme degrades enkaphalins in the brain, and studies in mouse suggest that it is involved in proteolytic events regulating the cell cycle. [provided by RefSeq, Jul 2008]
GeneCards Summary for NPEPPS Gene
NPEPPS (Aminopeptidase Puromycin Sensitive) is a Protein Coding gene. Among its related pathways are Immune System and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include metallopeptidase activity and aminopeptidase activity. An important paralog of this gene is ENPEP.
UniProtKB/Swiss-Prot for NPEPPS Gene
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 more efficiently than tau from Alzheimer disease brain.
