Probable downstream regulator of strigolactones signaling (By similarity). Functions in a complex with MODD and HDAC1 to down-regulate the histone acetylation level at BZIP46 target genes. BZIP46 is a positive regulator of abscisic acid (ABA) signaling and drought stress tolerance (PubMed:27468891). Tetramer (PubMed:26601214). Interacts with D53 (PubMed:24336200). Interacts with MODD and HDAC1 (PubMed:27468891). Interacts with WOX1 (PubMed:25697101, PubMed:24336200, PubMed:26601214, PubMed:27468891). Interacts with MOF1 (PubMed:32680975). Expressed in panicles, stems, leaves, spikelets and seed endosperm. Highest expression in endosperm at 21 days after pollination. The N-terminal TOPLESS domain (TPD) (1-209) binds directly to a 12-amino acid LxLxL EAR motif peptide.
