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.

textEndothelins (EDNs) are 21-amino acid vasoconstricting peptides produced primarily in the endothelium that play a key role in vascular homeostasis. An imbalance and over-expression of EDNs can contribute to hypertension (high blood pressure). EDNs are implicated in vascular diseases of several organ systems, including the heart, general circulation and brain. There are 3 isoforms derived from the genes EDN1, EDN2 and EDN3 (Inoue et al. 1989).

EDNs bind to two receptors (Elshourbagy et al. 1993), EDNRA (Adachi et al. 1991) and EDNRB (Nakamuta et al. 1991). EDNRA is primarily located in the smooth muscle of blood vessels. EDN binding to EDNRA results in vasoconstriction and sodium retention, leading to increased blood pressure. EDNRB is primarily located on endothelial cells lining the internal walls of vasculature. EDN binding to EDNRB leads to the release of NO (nitric oxide), a powerful vasodilator.
