MKK7 | Mitogen-activated protein kinase kinase 7; May function as a negative regulator of polar auxin transport. Positively regulates plant basal and systemic acquired resistance (SAR). Activates MPK3 and MPK6 in vitro. (307 aa) | ||||
MKK3 | Mitogen-activated protein kinase kinase 3; MKK3-MPK6 module plays an important role in the jasmonate signal transduction pathway through the negative regulation of MYC2/JIN1 expression. Activates by phosphorylation the downstream MPK6, MPK7 and MPK8. MKK3-MPK7 module acts as a positive regulator of PR1 gene expression. MKK3-MPK8 module negatively regulates ROS accumulation through controlling expression of the RBOHD gene. Component of the abscisic acid (ABA) signaling pathway that may act as ABA signal transducer in the context of abiotic stresses. Activator of the C group MAP kinases. [...] (520 aa) | ||||
MKK4 | Mitogen-activated protein kinase kinase 4; Involved in the second phase of hydrogen peroxide generation during hypersensitive response-like cell death. Involved in the innate immune MAP kinase signaling cascade (MEKK1, MKK4/MKK5 and MPK3/MPK6) downstream of bacterial flagellin receptor FLS2. Activates by phosphorylation the downstream MPK3 and MPK6. YDA-MKK4/MKK5-MPK3/MPK6 module regulates stomatal cell fate before the guard mother cell (GMC) is specified. This MAPK cascade also functions downstream of the ER receptor in regulating coordinated local cell proliferation, which shapes the [...] (366 aa) | ||||

MKK1 | Mitogen-activated protein kinase kinase 1; MEKK1, MKK1/MKK2 and MPK4/MPK6 function in a signaling pathway that modulates the expression of genes responding to biotic and abiotic stresses and also plays an important role in pathogen defense by negatively regulating innate immunity. Activates by phosphorylation the downstream MPK4. Acts redundantly with MKK2. MKK1-MPK6 module mediates abscisic acid (ABA)-dependent CAT1 expression with H(2)O(2) production and response to drought and salt stress. MKK1-MPK6 module is also involved in sugar signaling during the process of seed germination. (354 aa) | ||||
MKK6 | Mitogen-activated protein kinase kinase 6; 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. (356 aa) | ||||
MKK2 | Mitogen-activated protein kinase kinase 2; MEKK1, MKK1/MKK2 and MPK4 function in a signaling pathway that modulates the expression of genes responding to biotic and abiotic stresses and also plays an important role in pathogen defense by negatively regulating innate immunity. Plays a role in abiotic stress tolerance and plant disease resistance through activation of MPK4 and MPK6 by phosphorylation. Acts redundantly with MKK1. (363 aa) | ||||
MKK9 | Mitogen-activated protein kinase kinase 9; MKK9-MPK3/MPK6 module phosphorylates and activates EIN3, leading to the promotion of EIN3-mediated transcription in ethylene signaling.
