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.

| text | SUMOylation of MDC1 by PIAS4 creates a docking site for RNF4, an E3 ubiquitin ligase. RNF4 binds to MDC1 specifically when SUMO2 is attached to lysine K1840 of MDC1. RNF4 polyubiquitinates MDC1 through ubiquitin lysine residue K48 cross-linking. RNF4-mediated ubiquitination targets MDC1 for degradation and causes dissociation of MDC1-bound proteins from DNA double-strand breaks (DSBs). While additional regulation steps may be involved, the activity of RNF4 is necessary for the initiation of resection of DNA ends at DSBs and progression of homologous recombination (Luo et al. 2012, Yin et al. 2012, Galanty et al. 2012). |
