Source Description
UniProtTranscription activator that recognizes the motif 5'-TAACGG-3' in the promoter of endosperm-induced genes (PubMed:27681170, PubMed:25194028, PubMed:19066902). Promotes vegetative-to-embryonic transition and the formation of somatic embryos from root explants in a WUS-independent manner but via the expression of embryonic genes (e.g. LEC1, LEC2, FUS3 and WUS) (PubMed:18695688). May play an important role during embryogenesis and seed maturation (PubMed:19066902, PubMed:25194028). Together with MYB115, activates the transcription of S-ACP-DES2/AAD2 and S-ACP-DES3/AAD3 thus promoting the biosynthesis of omega-7 monounsaturated fatty acid in seed endosperm (PubMed:27681170). Regulates negatively maturation genes in the endosperm (PubMed:25194028). {ECO:0000269|PubMed:18695688, ECO:0000269|PubMed:19066902, ECO:0000269|PubMed:25194028, ECO:0000269|PubMed:27681170}.
