| Polycomb group protein EMBRYONIC FLOWER 2 | Polycomb group (PcG) protein. Involved in flowering processes by repressing unknown target genes and preventing reproductive development. Participates in polycomb group (PcG) protein complex-mediated (probably in complex with EMF1) 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, by mediating trimethylation of histone 3 lysine 27 on the AG chromatin (H3K27me3). PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. | probable | Q8L6Y4 |
