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.

textCCNA2:CDK1 complex was reported to phosphorylate CDC25B in late G2, targeting it for proteasome-mediated degradation, which is an important step for G2/M transition (Baldin et al. 1997). While CCNB1:CDK1 and CCNA2:CDK2 can also phosphorylate CDC25B, the phosphorylated residues likely differ for the three CDK2 complexes, based on differences in migration of phosphorylated CDC25B in denaturing polyacrylamide gels, and only CCNA2:CDK1-mediated phosphorylation leads to proteasomal degradation of CDC25B (Baldin et al. 1997). CDC25B (MPIP2) was also reproducibly identified as a target of the CCNA2:CDK1 complex in a high-throughput study (Dumitru et al. 2017).
