Binds A/T-rich DNA with a highly dynamic distribution into the nucleus. Follows a highly dynamic speckled distribution pattern throughout the chromatin of interphase nuclei. Mostly expressed in flowers (especially in styles and filaments, and, at lower levels, in sepals and ovaries) and developing siliques, and, to a lower extent, in leaves, cotyledons, lateral roots and root tips. Acetylated. Belongs to the HMGA family. Lacks phosphorylation sites present in ortholog HMGA proteins. Truncated N-terminus.
