    Summary
    Enables minor groove of adenine-thymine-rich DNA binding activity. Involved in female gonad morphogenesis; imaginal disc morphogenesis; and regulation of stem cell differentiation. Located in nucleus and polytene chromosome. Is expressed in several structures, including central nervous system; gut section; imaginal disc; tarsal segment; and visceral trunk mesoderm derivative.
