Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| comment | FUNCTION Plays a role in the cellular breakdown of insulin, APP peptides, IAPP peptides, natriuretic peptides, glucagon, bradykinin, kallidin, and other peptides, and thereby plays a role in intercellular peptide signaling (PubMed:10684867, PubMed:17051221, PubMed:17613531, PubMed:18986166, PubMed:19321446, PubMed:21098034, PubMed:2293021, PubMed:23922390, PubMed:24847884, PubMed:26394692, PubMed:26968463, PubMed:29596046). Substrate binding induces important conformation changes, making it possible to bind and degrade larger substrates, such as insulin (PubMed:23922390, PubMed:26394692, PubMed:29596046). Contributes to the regulation of peptide hormone signaling cascades and regulation of blood glucose homeostasis via its role in the degradation of insulin, glucagon and IAPP (By similarity). Plays a role in the degradation and clearance of APP-derived amyloidogenic peptides that are secreted by neurons and microglia (Probable) (PubMed:26394692, PubMed:9830016). Degrades the natriuretic peptides ANP, BNP and CNP, inactivating their ability to raise intracellular cGMP (PubMed:21098034). Also degrades an aberrant frameshifted 40-residue form of NPPA (fsNPPA) which is associated with familial atrial fibrillation in heterozygous patients (PubMed:21098034). Involved in antigen processing. Produces both the N terminus and the C terminus of MAGEA3-derived antigenic peptide (EVDPIGHLY) that is presented to cytotoxic T lymphocytes by MHC class I.FUNCTION (Microbial infection) The membrane-associated isoform acts as an entry receptor for varicella-zoster virus (VZV).CATALYTIC ACTIVITY Degradation of insulin, glucagon and other polypeptides. No action on proteins.COFACTOR Binds 1 zinc ion per subunit.ACTIVITY REGULATION Activated by small peptides (By similarity). Activated by ATP and GTP, and to a lesser extent by CTP, TTP and PPPi (PubMed:17613531). Inhibited by bacitracin (PubMed:17055432, PubMed:17613531). In vitro modification of Cys residues impairs enzyme activity (PubMed:18986166).SUBUNIT Homodimer (Probable) (PubMed:17051221, PubMed:19321446, PubMed:23922390, PubMed:26394692, PubMed:29596046). Can also form homotetramers (By similarity).SUBUNIT (Microbial infection) 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 (PubMed:17055432, PubMed:17553876).INTERACTION Present at the cell surface of neuron cells. The membrane-associated isoform is approximately 5 kDa larger than the known cytosolic isoform.ALTERNATIVE PRODUCTS Detected in brain and in cerebrospinal fluid (at protein level).DOMAIN The SlyX motif may be involved in the non-conventional secretion of the protein.PTM The N-terminus is blocked.MISCELLANEOUS ATP-binding induces a conformation change.SIMILARITY Belongs to the peptidase M16 family. |
