    at STAGE
  • an N terminal catalytic domain
  • a C terminus facilitating substrate recognition as well as playing a key role in the oligomerization of IDE
  • conjugated MetalloP
    mono polymer homomer , dimer
  • peptidase M16 family
  • CATEGORY enzyme
    text zinc metalloprotease found in the cytosol of all cells (Carpenter 2010)
    basic FUNCTION
  • may play a role in the cellular processing of insulin
  • may be involved in intercellular peptide signaling
  • involved in the termination of the insulin response
  • involved in the clearance of insulin and amyloid-beta
  • acting as a zinc metalloprotease involved in the degradation of the amyloid beta-peptide (Carpenter 2010)
  • exhibits a remarkable specificity to degrade insulin without breaking the disulfide bonds that hold the insulin A and B chains together (Manolopoulou 2009)
    a component
  • complex with four substrates (insulin B chain, amyloid-beta peptide (1-40), amylin and glucagon)
    small molecule metal binding,
  • one zinc ion per subunit
  • protein
  • binds to the nonglycosylated precursor of varicella-zoster virus gE protein found in the endoplasmic reticulum (Carpenter 2010)
  • IAPP is also a known substrate of the protease insulin-degrading enzyme (IDE)
  • cell & other
    inhibited by potently by physiologically relevant concentrations of S-nitrosylation and oxidation agents (Malito 2008)
