Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor. Plays a crucial role in tapetum development. Required for male fertility and pollen differentiation, especially during the post-meiotic transcriptional regulation of microspore development within the developing anther (PubMed:12535353). Binds E-box regions in the AHL16/TEK promoter. {ECO:0000269\|PubMed:12535353, ECO:0000269\|PubMed:24804694}.
