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. Interacts with KIN10 and KIN11 via its FLZ-type zinc finger domain (PubMed:24600465, PubMed:29945970). Interacts with KINB1, KINB2, KINB3 and SNF4 via its N-terminal part (PubMed:29945970). Shuttles from the cytoplasm to the nucleus when associated with KIN10. Down-regulated by NaCl. Belongs to the FLZ family. Truncated N-terminus. Truncated N-terminus.
