Dipeptidase 3 (DPEP3) is a protein that in humans is encoded by the DPEP3gene.
This gene encodes a membrane-bound glycoprotein from the family of dipeptidases (EC 188.8.131.52) involved in hydrolytic metabolism of various dipeptides, including penem and carbapenembeta-lactam antibiotics. This gene is located on chromosome 16 in a cluster with another member of this family, DPEP2. Alternatively spliced transcript variants that encode different isoforms have been found for this gene.
