NCBI Protein Information
MAP kinase/ ERK kinase 1
NCBI Summary
Member of MAP Kinase Kinase. Likely functions in a stress-activated MAPK pathway. Can phosphorylate the MAPK AtMPK4, in response to stress. Gets phosphorylated by MEKK1 in response to wounding.

UniProt Comments
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 H2O2 production and response to drought and salt stress. MKK1-MPK6 module is also involved in sugar signaling during the process of seed germination.
