==Crystal structure of the zinc finger associated domain of the Drosophila transcription factor Grauzone==
-
About one-third of the more than 300 C2H2 zinc finger proteins of, Drosophila contain a conserved sequence motif, the zinc finger-associated, domain (ZAD). Genes that encode ZAD proteins are specific for and expanded, in the genomes of insects. Only three ZAD-encoding gene functions are, established, and the role of ZAD is unknown. Here we present the crystal, structure of the ZAD of Grauzone (ZAD(Grau)), a Drosophila transcription, factor that specifically controls the maternal Cdc20-like APC subunit, Cortex. ZAD forms an atypical treble-clef-like zinc-coordinating fold., Head-to-tail arrangement of two ZAD(Grau) molecules in the crystals, suggests dimer formation, an observation supported by crosslinking and, dynamic light scattering. The results indicate that ZAD provides a novel, protein-protein interaction module that characterizes a large family of, insect transcription factors.
