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.

commentFUNCTION Receptor that signals constitutively via several signaling pathways including PI3K/AKT as well as mitogen- and stress-activated/MAP kinases. Promotes host cell proliferation and survival, modulates cell migration, stimulates angiogenesis, and recruits inflammatory cells, both in expressing cells and in neighboring cells. Maintains chronic activation of NF-kappa-B via interaction with host CADM1 (PubMed:29698475).SUBUNIT Interacts with protein K7; this interaction promotes vGPCR proteasomal degradation (PubMed:18802460). Interacts with host CADM1; this interaction is essential for chronic NF-kappa-B activation (PubMed:29698475).INTERACTION Belongs to the G-protein coupled receptor 1 family.
