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). Involved in seed dormancy control (PubMed:15159630). Interacts with KIN10 and KIN11 via its FLZ-type zinc finger domain (PubMed:24600465, Ref.12, PubMed:29945970). Interacts with KINB1 and KINB2 via its N-terminal part (PubMed:29945970). Interacts with TZF4, TZF5 and TZF6 (PubMed:26978070). Interacts with MPK3 and MPK6 (Ref.12). Expressed at very low levels during early stages of leaf development, but up-regulated during leaf senescence. Up-regulated by abscisic acid (PubMed:11402199, PubMed:15159630). Down-regulated by the transcription factor ERF114 (PubMed:23616605). Down-regulated by glucose, sucrose and mannose (PubMed:26442059). Induced by abscissic acid (ABA) (PubMed:26442059). No visible phenotype, but reduced dormancy and fast germination of the seeds. Strong resistance of the seeds to abscisic acid. Belongs to the FLZ family. Truncated N-terminus. Truncated N-terminus.
