Description
Transcription repressor that regulates phase transition during shoot, flower and seeds development. Controls leaves development, shoot architecture and flowering by delaying both the vegetative to reproductive transition and flower initiation. Participates in polycomb group (PcG) protein complex-mediated (including EMF2) silencing of the flower homeotic genes AGAMOUS (AG), PISTILLATA (PI), and APETALA3 (AP3), as well as of some regulatory genes such as ABSCISIC ACID INSENSITIVE3 (ABI3), LONG VEGETATIVE PHASE1 (LOV1), and FLOWERING LOCUS C (FLC) during vegetative development. Required for histone methylation or for maintaining a stable histone methylation (e.g. H3K27me3) pattern of repressed target genes. Can bind non specifically DNA (both double- and single-stranded) and RNA.
