Alignment of soybean NF-YA domains. The referred sequences are from Arabidopsis (At), Medicago (Mt), human (Hs), mouse (Rn) and yeast (Sc). Numbers in parentheses are the actual amino acid numbers of the start and end of NF-YA domain. Required amino acids (Required AA) are important for DNA binding and subunit interaction from yeast (Xing et al. 1993) and rat (Maity and de Crombrugghe 1992). The three boxes in green are the basic residual clusters required for nuclear targeting (Peng et al. 1998) (color figure online)
