Function

[EBS_ARATH] 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).^{[1] [2] [3]}
