    ..We show that dpp can promote ventral fates in Xenopus, and that injection of sog mRNA counteracts the ventralizing effects of dpp. These results suggest the molecular conservation of dorsoventral patterning mechanisms during evolution. ..

    ..Thus, the very similar chaperone activities of the two proteins, uncovered through in vitro analysis, diverge in vivo in specific signal transduction pathways. ..
  4. Palopoli M, Patel N. Evolution of the interaction between Hox genes and a downstream target. Curr Biol. 1998;8:587-90 pubmed

  5. Llopart A, Elwyn S, Coyne J. Pigmentation and mate choice in Drosophila. Nature. 2002;419:360; discussion 360 pubmed
    ..Here we show that the mate discrimination observed by Kopp et al. may in fact have resulted from the nature of the strains and comparisons they used in their study and so could be irrelevant to mate choice in nature. ..
  6. Nicolay B, Frolov M. Context-dependent requirement for dE2F during oncogenic proliferation. PLoS Genet. 2008;4:e1000205 pubmed publisher
    ..Thus, we uncovered a critical requirement for the dE2F family during inappropriate proliferation of Hippo pathway mutant cells. ..

    ..1-kb mRNAs suggests that the Ovo and Svb proteins share DNA-binding specificity conferred by four Cys2-His2 zinc finger motifs but differ functionally in their capacity to interact with other components of the transcription machinery. ..
