Identification
HMDB Protein ID HMDBP10019
Secondary Accession Numbers
  • 15958
Name Insulin-degrading enzyme
Synonyms
  1. Abeta-degrading protease
  2. Insulin protease
  3. Insulinase
  4. Insulysin
Gene Name IDE
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific Function Plays a role in the cellular breakdown of insulin, IAPP, glucagon, bradykinin, kallidin and other peptides, and thereby plays a role in intercellular peptide signaling. Degrades amyloid formed by APP and IAPP. May play a role in the degradation and clearance of naturally secreted amyloid beta-protein by neurons and microglia
