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 | WEE1-mediated tyrosine phosphorylation of CDK1 (Cdc2) bound to either CCNA or CCNB was initially discovered using human CDK1, clam cyclin A or cyclin B, and wee1 from Schizosaccharomyces pombe (Parker et al., 1991). The human WEE1 kinase was subsequently shown to phosphorylates CDK1 on tyrosine 15 (Y15), resulting in inactivation of the CCNB1:CDK1 complex (Watanabe et al., 1995). Two-dimensional gel electrophoresis of protein extracts of cycling human cells has shown that CDK1 triple phosphorylated at T14, Y15, and T161 is the most abundant form of CDK1 that co-immunoprecipitates with CCNA2 or CCNB1, and Y15 phosphorylation of CDK1 was confirmed to be WEE1-dependent (Coulonval et al. 2011). WEE1 inhibition in G2 by a tyrosine kinase inhibitor MK-1775 decreases Y15 phosphorylation on CCNA2-bound CDK1 and CDK2 and promotes the activity of CCNA2:CDK complexes (Gheghiani et al. 2017). |
