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 Cyclin-dependent protein kinase (CDK) inhibitor that functions as a repressor of mitosis in the endoreduplication cell cycle (PubMed:10952891, PubMed:11882294, PubMed:17098811, PubMed:17764505, PubMed:19717615, PubMed:20194967). Inhibits the kinase activity of CYCD3-1/CDKA-1, CYCD2-1/CDKA-1 and CYCB1-1/CDKB1-1 complexes in a dose dependent manner (PubMed:26546445). Cooperates with SMR1 and SMR2 to promote endoreplication during leaf development (PubMed:26546445). Required for normal trichome endoreplicating cell cycles (PubMed:10952891, PubMed:11882294, PubMed:17098811, PubMed:17764505, PubMed:19717615, PubMed:20194967). Positive regulator of effector-triggered immunity (ETI) (PubMed:25455564).SUBUNIT Interacts with CDKA-1 (PubMed:17098811, PubMed:26546445). Interacts with CYCD2-1, CYCD3-2 and CYCD4-1 (PubMed:17098811). Interacts with CDKB1-1 (PubMed:20706207, PubMed:26546445). Interacts with CPR5 (PubMed:25455564).SUBCELLULAR LOCATION Expressed in the shoot apical meristem, leaf primordia and the elongation zone of the root.INDUCTION Down-regulated by gibberellin (PubMed:19576768). Up-regulated by zeocin treatment (PubMed:21613568).DISRUPTION PHENOTYPE Multicellular trichomes with nuclei showing reduced levels of endoreduplication.MISCELLANEOUS Plants over-expressing SIM are dwarf with serrated leaves containing enlarged cells with increased levels of nuclear DNA.
