Multiplicity of the DNA-binding protein HBP-1 specific to the conserved hexameric sequence ACGTCA in various plant gene promoters.
A novel DNA-binding protein that specifically interacts with the hexameric sequence ACGTCA in the regulatory region of the wheat histone H3 gene has been identified in wheat nuclear extract and designated HBP-1a. The nuclear protein HBP-1 previously identified as a DNA-binding protein that interacts with hexameric sequences in the H3, cauliflower mosaic virus (CaMV) 35 S RNA, and nopaline synthase (NOS) promoter regions therefore has been renamed HBP-1b. The flanking sequences that surround the hexameric sequence may account for the difference in the binding properties of HBP-1a and HBP-1b.
