Functional Description ? help Back to Top
Source	Description
UniProt	Transcription activator (PubMed:24278028). Binds to 5'-CAACTGTC-3' and/or 5'-TAACAAA-3' motif in target gene promoter to promote their expression (By similarity). Together with MYB97 and MYB101, functions as a male factor that controls pollen tube-synergid interaction in fertilization. Required for pollen tube growth arrest and sperm cell release in the female gametophyte, probably via the regulation of pollen tube-specific gene expression (PubMed:24278028, PubMed:23791732). {ECO:0000250\|UniProtKB:O80883, ECO:0000269\|PubMed:23791732, ECO:0000269\|PubMed:24278028}.
