ID:IDE_HUMAN DESCRIPTION: RecName: Full=Insulin-degrading enzyme; EC=3.4.24.56; AltName: Full=Abeta-degrading protease; AltName: Full=Insulin protease; Short=Insulinase; AltName: Full=Insulysin; 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. CATALYTIC ACTIVITY: Degradation of insulin, glucagon and other polypeptides. No action on proteins. COFACTOR: Binds 1 zinc ion per subunit. ENZYME REGULATION: Activated by small peptides (By similarity). Activated by ATP and GTP, and to a lesser extent by CTP, TTP and PPPi. Inhibited by bacitracin. Inhibited by S-nitrosylation and oxidation agents. SUBUNIT: Homodimer. Can form higher oligomers. Interacts (via N- terminus) with varicella-zoster virus (VZV) envelope glycoprotein E (via N-terminus); the membrane-associated isoform may function as an entry receptor for this virus. SUBCELLULAR LOCATION: Cytoplasm. Cell membrane. Secreted (By similarity). Note=Present at the cell surface of neuron cells. The membrane-associated isoform is approximately 5 kDa larger than the known cytosolic isoform. DOMAIN: The SlyX motif may be involved in the non-conventional secretion of the protein (By similarity). PTM: The N-terminus is blocked. MISCELLANEOUS: ATP-binding induces a conformation change. SIMILARITY: Belongs to the peptidase M16 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
