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.

textproPGA4 (pepsin A-4 precursor) catalyzes its own hydrolysis to yield PGA4 and a propeptide. In the body, the precursor protein is synthesized in gastric chief cells. As it is released into the lumen of the stomach, the low stomach pH induced a conformational change that exposes the protein's active site and the peptide bond between residues 62 and 63 of the precursor protein is cleaved to yield the mature catalytically active pepsin and a propeptide of no known function (Athuada et al. 1989; Foltmann 1988).
