Trans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3' (By similarity). May play a role in plant development. Binds 2 Zn(2+) ions per subunit. Mostly located in the nucleus. Expressed in vasculature of aerial parts. Expressed in cotyledons and leaf petioles. The SBP-type zinc finger is required for the binding to DNA. Plants display elongated petioles and enhanced leaf margin serration and are able to germinate and develop in the presence of the programmed cell death (PCD)-inducing fungal toxin fumonisin B1 (FB1).
