May act as an adapter to facilitate the interaction of SnRK1 complex with effector proteins, conferring tissue- and stimulus-type specific differences in the SnRK1 regulation pathway (PubMed:24600465). Negatively regulates KIN10 leading to a repression of the SnRK1 signaling pathway (PubMed:29406622). Interacts with KIN10 and KIN11 via its FLZ-type zinc finger domain. Shuttles from the cytoplasm to the nucleus when associated with KIN10 (PubMed:24600465). Co-localized with ER marker when associated with KIN11 (PubMed:29406622). Early expressed in hypocotyl and cotyledon. Later expressed in old or senescing leaves and in pistil, pollen and filament of open flowers. Up-regulated in response to prolonged energy depletion (PubMed:26442059, PubMed:29406622). Up-regulated by the glycolysis inhibitor 2DG (PubMed:26442059). Induced by abscissic acid (ABA) (PubMed:29406622). Reduced biomass and lateral roots and shorter primary roots. Belongs to the FLZ family.
