Gene: XPNPEP3 (X-prolyl aminopeptidase 3) Homo sapiens
Symbol: XPNPEP3
Name: X-prolyl aminopeptidase 3
Description: Exhibits manganese ion binding activity; metalloaminopeptidase activity; and protein homodimerization activity. Involved in glomerular filtration and protein processing. Localizes to mitochondrion. Implicated in nephronophthisis-like nephropathy 1.
Type: protein-coding
RefSeq Status: REVIEWED
