SNF1-related kinases (SnRK1s) play central roles in coordinating energy balance and nutrient metabolism in plants. SNF1 and AMPK, the SnRK1 homologs in budding yeast (Saccharomyces cerevisiae) and mammals, are activated by phosphorylation of conserved threonine residues in their activation loops. Arabidopsis (Arabidopsis thaliana) GRIK1 and GRIK2, which were first characterized as geminivirus Rep interacting kinases, are phylogenetically related to SNF1 and AMPK activating kinases.
