UniProt Comments
Dual-function transcription factor with both repression and activation activities. Binds to 5'-CCATATT-3' motif in target gene promoters (e.g. ABR1) (PubMed:26961720). Binds also to G-rich DNA motif 5'-GGGGGCAGTGG-3' (PubMed:22508367). Regulates the expression of genes involved in diverse cellular pathways, including glucose metabolism, photosynthesis, phototropism and stress response (e.g. salt, drought and osmotic stress) (PubMed:22508367, PubMed:26961720). Regulates plant immunity, especially during necrotrophic fungal infection (e.g. B.cinerea) (PubMed:24451981). Binds to ABR1 promoter and promotes its expression, thus negatively regulating the abscisic acid (ABA) signaling pathway. Represses ABA- and salt-responsive genes expression (PubMed:26961720).
