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.

textCBX4 (Pc2) SUMOylates HNRNPK at lysine-422 with SUMO2 (Li et al. 2004, Lee et al. 2012, Pelisch et al. 2012, Hendriks et al. 2014, Impens et al. 2014, Tammsalu et al. 2014). (Two molecules of SUMO2 are shown in the reaction in order to represent the oligomeric chains of SUMO2 that are attached to a target protein.) PIAS3 also SUMOylates HNRNPK predominantly with SUMO1 (Lee et al. 2012). HNRNPK is SUMOylated in response to DNA damage and SUMOylation is regulated by HIPK2 and CBX4. SUMOylation of HNRNPK is required for coactivation of TP53 (p53) activated transcription. SUMOylation increases the stability of HNRNPK, the nonSUMOylated form of which is normally ubiquinated by HDM2 (Lee et al. 2012).
