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:29945970). Interacts with KINB1, KINB2, KINB3 and SNF4 via its N-terminal part (PubMed:29945970). Interacts with HB21/ZHD3 (Ref.8). Down-regulated in response to mild as well as prolonged energy depletion (PubMed:26442059). Up-regulated by glucose and sucrose (PubMed:26442059). Belongs to the FLZ family. Truncated N-terminus.
