General annotation (Comments)

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. Ref.7 Ref.13 Ref.14

Catalytic activity

Degradation of insulin, glucagon and other polypeptides. No action on proteins. Ref.13

Cofactor

Binds 1 zinc ion per subunit. Ref.12

Enzyme regulation

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. Ref.13 Ref.14

Subunit structure

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. Ref.8 Ref.9 Ref.12 Ref.13

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. Ref.7 Ref.8

Domain

The SlyX motif may be involved in the non-conventional secretion of the protein By similarity.

Post-translational modification

The N-terminus is blocked.

Miscellaneous

ATP-binding induces a conformation change.

Sequence similarities

Belongs to the peptidase M16 family.
