Chromatin remodeling factor that binds to methylated histone (e.g. H3K4me2/3) to prevent their acetylation (e.g. H3K9K14Ac), likely by recruiting histone deacetylase (HDAC) complexes, and thus regulating the transcription of target genes (PubMed:25281686). Negative regulator in developmental processes in a gibberellic acid- (GA-) dependent manner, such as germination, flowering induction, and flower organ specification, probably by modulating developmental gene expression (PubMed:11340178, PubMed:25281686). Involved in the chromatin-mediated repression of floral initiation and controls genes regulating flowering (PubMed:25281686). Negatively regulates the expression of the floral integrator FT epigenetically, by preventing high levels of H3 acetylation, thus maintaining an inactive chromatin conformation at FT locus (PubMed:25281686, PubMed:12837946). Recognizes di- and trimethylated histone H3 at lysine 4 (H3K4me2 and H3K4me3). Interacts with HDA6. Expressed ubiquitously, with higher levels in floral buds. Expressed at all stages of development, from seedlings to adult reproductive phase, throughout the shoot apical meristem and young primordia. Higher H3K9K14 acetylation in the genomic region of the FT locus leading to an enhanced accumulation (PubMed:25281686, PubMed:12837946). In ebs-2, acceleration of flowering associated with a shorter adult vegetative phase (PubMed:11340178, PubMed:12837946, PubMed:25281686). Other developmental defects include smaller leaves and siliques, reduction in seed dormancy, plant size, and fertility, and partial suppression of LEAFY disruption (e.g. lfy-6) effects (PubMed:11340178, PubMed:25281686). Belongs to the SHL1/EBS protein family.
