MMK1 — Cucumis sativus

Summary

CSA_6G365750, designated MMK1 in cucumber (Cucumis sativus, chromosome 6), encodes a mitogen-activated protein kinase (MAPK) with MAPKK activity (EC 2.7.11.24), protein serine/threonine kinase activity, and ATP binding. The gene is associated with the MAPK cascade, intracellular signal transduction, and the PRR signaling pathway. It has been linked to sex differentiation and determination, as well as responses to UV-C, fungi, and salinity. Additional associations include leaf senescence, seed germination, stomatal closure, cell death, and the anabolism of lignin, ethylene, and phenylpropanoids. The protein localizes to both the cytoplasm and nucleus. Related genes in other species link the family to root elongation and vegetative development.
