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.

textThe exopeptidase Carboxypeptidase E (CPE, also called Carboxypeptidase H) successively cleaves the C terminal arginine 89 and lysine 88 from insulin(57-89) to yield C peptide, which is released in equimolar amounts with mature insulin by vesicle exocytosis. The biochemical details of this reaction have been worked out for the rat protein (Davidson & Hutton 1987) and studies of variant forms of the human protein suggest the same function for human CPE Chen et al. 2001). The reaction occurs in immature secretory granules (Orci et al. 1985).
