XPNPEP1 - X-prolyl aminopeptidase 1 Gene
Also Known as APP1; SAMP; XPNPEP; XPNPEPL; XPNPEPL1
Species: Homo sapiens
About XPNPEP1
This gene has 29 transcripts (splice variants), 213 orthologues and 7 paralogues. Ubiquitous expression in small intestine (RPKM 32.0), duodenum (RPKM 25.3) and 25 other tissues.
Summary
This gene encodes the cytosolic form of a metalloaminopeptidase that catalyzes the cleavage of the N-terminal amino acid adjacent to a proline residue. The gene product may play a role in degradation and maturation of tachykinins, neuropeptides, and peptide Hormones. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Nov 2009]
