Function
Transcription repressor subunit of the SEU-SLK1 and SEU-SLK2 transcriptional corepressor of abiotic stress (e.g. salt and osmotic stress) response genes, by means of an epigenetic process involving histone modification (e.g. H3K9 and H3K14 acetylation), probably by recruiting HDAC, to facilitate the condensation of chromatin thus preventing transcription at the target genes (PubMed:24564815). Can also act as a transcription activator (PubMed:21518777). Implicated in embryo and floral development (PubMed:18390806). Involved in post-synthesis cell wall modifications necessary for mucilage extrusion from seeds upon imbibition, probably by promoting the expression of genes required for mucilage maturation (e.g. MUM2) (PubMed:11706181, PubMed:21362134, PubMed:21402796, PubMed:21518777). Regulates the maintenance on leaf polarity and meristem activity as well as the initiation of embryonic shoot apical meristem (SAM) development (PubMed:19837869).
