May be involved in the proteolytic inactivation of enkephalins and neurotensin in some brain areas. May convert inactive angiotensin I into the biologically active angiotensin II . Releases a C-terminal amino acid, with preference for large hydrophobic C-terminal amino acids and shows only very weak activity toward small amino acids and histidine .
Subcellular locations: Secreted, Extracellular space, Extracellular matrix
Expressed in the hippocampus, nucleus raphe, and cortex.
