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 The ANPs-MKK6-MPK4 module is involved in the regulation of plant cytokinesis during meiosis and mitosis. MKK6-MPK13 module positively regulates lateral root formation. Phosphorylates and activates MPK4. Activates MPK5 and MPK13 in vitro.CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-tyrosyl-[protein] + ATP = O-phospho-L-tyrosyl-[protein] + ADP + H(+)ACTIVITY REGULATION Activated through serine and threonine phosphorylation.SUBUNIT Interacts with P.syringae type III effector HopF2. Interacts with MPK4, MPK6, MPK11 and MPK13. Interacts with ANP3.INTERACTION Localized at the equatorial plane of the phragmoplast.TISSUE SPECIFICITY Expressed in roots, stems and flower buds. Higher levels in shoot apices and flowers.PTM Phosphorylation at Ser-221 and Thr-227 by MAP kinase kinase kinases positively regulates kinase activity.DISRUPTION PHENOTYPE Plants exhibit a dwarf phenotype with fewer flowers, large cells with multiple nuclei in various organs and large malformed pollen grains. Defects in the formation of the cell plate. RNAi MKK6 displays fewer lateral roots.SIMILARITY Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.
