Protein

Serine/threonine-protein kinase GRIK1

Gene

GRIK1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Activates SnRK1.1/KIN10 and SnRK1.2/KIN11 by phosphorylation of their activation-loop 'Thr-198' and 'Thr-176', respectively. Required for the regulation by SnRK1 kinases of the transcription of a large set of genes, the modification the activity of metabolic enzymes, and the control of various nutrient-responsive cellular developmental processes.5 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

Activated when autophosphorylated at Thr-154 and inactivated when phosphorylated at Ser-261 by SnRK1.1/KIN10.1 Publication
