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 Dual-specificity phosphatase involved in DNA damage response. Essential regulator of the G2 DNA damage checkpoint: following DNA damage, translocates to the nucleus and dephosphorylates FZR1/CDH1, a key activator of the anaphase promoting complex/cyclosome (APC/C). Dephosphorylates SIRT2 around early anaphase. Dephosphorylation of FZR1/CDH1 activates the APC/C, leading to the ubiquitination of PLK1, preventing entry into mitosis. Preferentially dephosphorylates proteins modified by proline-directed kinases.CATALYTIC ACTIVITY O-phospho-L-tyrosyl-[protein] + H2O = L-tyrosyl-[protein] + phosphateCATALYTIC ACTIVITY O-phospho-L-seryl-[protein] + H2O = L-seryl-[protein] + phosphateCATALYTIC ACTIVITY O-phospho-L-threonyl-[protein] + H2O = L-threonyl-[protein] + phosphateSUBUNIT Interacts with FZR1/CDH1.INTERACTION Following DNA damage, translocates from the nucleolus to the nucleoplasm and interacts with FZR1/CDH1.ALTERNATIVE PRODUCTS Composed of two structurally equivalent A and B domains that adopt a dual specificity protein phosphatase (DSP) fold.SIMILARITY Belongs to the protein-tyrosine phosphatase family. Non-receptor class CDC14 subfamily.
