Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that binds to the motif 5'-GTAACNT-3' in the promoter of target genes (e.g. DD11 and DD18) and promotes their expression within synergid cells (e.g. in the filiform apparatus) in ovules (PubMed:16214903, PubMed:17693534, PubMed:18410484, PubMed:17937500). Required for the formation of the filiform apparatus during synergid cell differentiation in the female gametophyte (PubMed:16214903). Involved in pollen tube guidance to the micropyle (PubMed:16214903, PubMed:17937500, PubMed:23093426). {ECO:0000269\|PubMed:16214903, ECO:0000269\|PubMed:17693534, ECO:0000269\|PubMed:17937500, ECO:0000269\|PubMed:18410484, ECO:0000269\|PubMed:23093426}.
