Protein

Mitogen-activated protein kinase kinase 7

Gene

MKK7

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.3 Publications

Miscellaneous

Overexpression of MKK5 (mutant bud1) causes deficiency in polar auxin transport and leads to plant architectural abnormality (PubMed:16377756). The bud1 mutant accumulates elevated levels of SA, and exhibits constitutive PR gene expression and enhanced resistance to both bacterial and oomycete pathogens (PubMed:17908155).2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.
