Function

IDE_HUMAN 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.^[1] ^[2] ^[3]

Publication Abstract from PubMed

Insulin-degrading enzyme (IDE) is a protease that cleaves insulin and other bioactive peptides such as amyloid-beta. Knockout and genetic studies have linked IDE to Alzheimer's disease and type-2 diabetes. As the major insulin-degrading protease, IDE is a candidate drug target in diabetes. Here we have used kinetic target-guided synthesis to design the first catalytic site inhibitor of IDE suitable for in vivo studies (BDM44768). Crystallographic and small angle X-ray scattering analyses show that it locks IDE in a closed conformation. Among a panel of metalloproteases, BDM44768 selectively inhibits IDE. Acute treatment of mice with BDM44768 increases insulin signalling and surprisingly impairs glucose tolerance in an IDE-dependent manner. These results confirm that IDE is involved in pathways that modulate short-term glucose homeostasis, but casts doubt on the general usefulness of the inhibition of IDE catalytic activity to treat diabetes.

Catalytic site inhibition of insulin-degrading enzyme by a small molecule induces glucose intolerance in mice.,Deprez-Poulain R, Hennuyer N, Bosc D, Liang WG, Enee E, Marechal X, Charton J, Totobenazara J, Berte G, Jahklal J, Verdelet T, Dumont J, Dassonneville S, Woitrain E, Gauriot M, Paquet C, Duplan I, Hermant P, Cantrelle FX, Sevin E, Culot M, Landry V, Herledan A, Piveteau C, Lippens G, Leroux F, Tang WJ, van Endert P, Staels B, Deprez B Nat Commun. 2015 Sep 23;6:8250. doi: 10.1038/ncomms9250.
