== Publication Abstract from PubMed ==
Male- and female-specific isoforms of the Doublesex (DSX) transcription factor regulate somatic sexual differentiation in Drosophila. The isoforms (DSX(M) and DSX(F)) share an N-terminal DNA binding domain (the DM motif), broadly conserved among metazoan sex-determining pathways. DM-DNA recognition is enhanced by a C-terminal dimerization domain. The crystal structure of this domain, determined at a resolution of 1.6 A, reveals a novel dimeric arrangement of ubiquitin-associated (UBA) folds. Although this alpha-helical motif is well characterized in pathways of DNA repair and subcellular trafficking, to our knowledge this is its first report in a transcription factor. Dimerization is mediated by a non-canonical hydrophobic interface extrinsic to the putative ubiquitin binding surface. Key side chains at this interface, identified by alanine scanning mutagenesis, are conserved among DSX homologs. The mechanism of dimerization is thus unrelated to the low affinity domain swapping observed among ubiquitin-associated CUE domains. The unexpected observation of a ubiquitin-associated fold in DSX extends the repertoire of alpha-helical dimerization elements in transcription factors. The possibility that the ubiquitination machinery participates in the regulation of sexual dimorphism is discussed.

Structural highlights

1zv1 is a 2 chain structure with sequence from Drosophila melanogaster. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.6Å

Function

DSX_DROME Controls somatic sexual differentiation. Binds directly and specifically to the FBE (fat body enhancer) of the yolk protein 1 and 2 genes (Yp1 and Yp2). This enhancer is sufficient to direct the female-specific transcription characteristic of the Yp genes in adult fat bodies. Involved in regulation of male-specific expression of takeout in brain-associated fat body.[1]
