Using an in vivo assay for segment identity, the structural differences that distinguish two Drosophila homeotic selector proteins, Ultrabithorax (Ubx) and Antennapedia (Antp), have been investigated. There are at least two independent parts of Ubx and Antp that contribute to their functional specificities: (1) their homeo domains and (2) residues carboxy… CONTINUE READING
