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.

textAntiviral innate immune response receptor RIG-I (RIG-1, DDX58) signaling is regulated by a dynamic balance between phosphorylation and dephosphorylation of CARDs and repressor domain (RD) of DDX58. While phosphorylation of DDX58 at S8 and T170 inhibited downstream signaling in human embryonic kidney 293T (HEK293T) cells and human monocytic THP-1 cells (Nistal-Villán E et al. 2010; Maharaj NP et al. 2012), dephosphorylation of DDX58 by PPP1CA and PPP1CC activated DDX58 to elicit immune signaling upon RNA virus infections (Wies E et al. 2013). Similar findings were reported in the studies with DDX58 phosphorylated at S854, S855 and T770 by casein kinase II in HEK293T cells and human umbilical vein endothelial cells (HUVEC) (Sun Z et al. 2011). Inhibition of phosphatase activity decreased virus-induced IFN-β production in human cells in a dose-dependent manner (Sun Z et al. 2011; Wies E et al. 2013).
