Background: Aminopeptidase P1/XPNPEP1

The human XPNPEP1 gene encodes aminopeptidase P1 (APP1), which is also known as X-prolyl aminopeptidase with gene aliases of SAMP, XPNPEP, XPNPEPL, and XPNPEPL1 (1‑3). It is a member of the M24 family of metalloproteases, which also contains methionine aminopeptidases, X-Pro dipeptidase, aminopeptidase P2, aminopeptidase P homolog, proliferation-associated protein 1, and suppressor of Ty homolog or chromatin-specific transcription elongation factor large subunit (4). It is a soluble enzyme, in contrast to the GPI-anchored APP2 encoded by XPNPEP2 (5). Human APP1 is widely expressed (3). The purified rhAPP1 is an active aminopeptidase, removing a N‑terminal amino acid from a peptide that contains a Pro residue at the second position. The amino acid sequence of human APP1 is 99%, 97%, 95%, 74% and 73% identical to that of canine, bovine, mouse/rat, Xenopus and zebrafish, respectively.
