  2. IRAP
  3. Insulin-regulated membrane aminopeptidase
  4. Insulin-responsive aminopeptidase
  5. Leucyl-cystinyl aminopeptidase, pregnancy serum form
  6. OTase
  7. Oxytocinase
  8. P-LAP
  9. Placental leucine aminopeptidase
Gene Name LNPEP
Protein Type Unknown
Biological Properties
General Function Involved in proteolysis
Specific Function Release of an N-terminal amino acid, cleaves before cysteine, leucine as well as other amino acids. Degrades peptide hormones such as oxytocin, vasopressin and angiotensin III, and plays a role in maintaining homeostasis during pregnancy. May be involved in the inactivation of neuronal peptides in the brain. Cleaves Met-enkephalin and dynorphin. Binds angiotensin IV and may be the angiotensin IV receptor in the brain
