CC -!- FUNCTION: Involved in ABA and stress responses and acts as a positive
CC component of glucose signal transduction. Functions as a
CC transcriptional activator in the ABA-inducible expression of rd29B.
CC Binds specifically to the ABA-responsive element (ABRE) of the rd29B
CC gene promoter. {ECO:0000269|PubMed:11005831,

CC ECO:0000269|PubMed:16463099}.
CC -!- SUBUNIT: DNA-binding heterodimer (By similarity). Interacts with ARIA.
CC {ECO:0000250, ECO:0000269|PubMed:15516505}.
CC -!- INTERACTION:
CC Q9M7Q4; Q940H6: SRK2E; NbExp=2; IntAct=EBI-1538369, EBI-782514;

CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=Q9M7Q4-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves, flowers and siliques
CC but not in seeds. {ECO:0000269|PubMed:11005831,
CC ECO:0000269|PubMed:15361142, ECO:0000269|PubMed:16284313}.
CC -!- INDUCTION: Up-regulated by drought, salt, abscisic acid (ABA), cold and
CC glucose. {ECO:0000269|PubMed:10636868, ECO:0000269|PubMed:11005831,

CC -!- PTM: The activation by phosphorylation is induced by abscisic acid
CC (ABA). Phosphorylated by SRK2C, SRK2D, SRK2E, SRK2F and SRK2I in vitro.
CC {ECO:0000269|PubMed:17307925}.
