MKK3 — Brachypodium distachyon

Summary

BRADI_4G39490V3 (MKK3-1, also known as BdMKK3) on chromosome 4 of false brome encodes a mitogen-activated protein kinase kinase with MAPKK activity (EC 2.7.12.2), also annotated with MEKK activity, protein serine/threonine kinase activity, and DNA-binding transcription factor activity. The protein contains a protein kinase domain and an NTF2-like domain superfamily. MKK3-1 is associated with the MAPK cascade, regulation of defense response to insects, response to herbivore, induced systemic resistance mediated by ethylene and jasmonic acid signaling, downregulation of stomatal opening, positive regulation of leaf senescence, and response to desiccation. It is linked to traits including drought tolerance, salt tolerance, aphid response, insect damage response, seed protein content, photosynthetic rate, flowering time, leaf senescence, root morphology, and shoot elongation under submergence. The protein localizes to the nucleus, cytoplasm, plasmalemma, and nucleolus.
