Understanding the regulation of human gene expression requires knowledge of the "second genetic code," which consists of the binding specificities of transcription factors (TFs) and the combinatorial code by which TF binding sites are assembled to form tissue-specific enhancer elements. Using a novel high-throughput method, we determined the DNA binding(More)
We identified the mouse homolog of human DRAPC1 (APCDD1) gene, shown to be a target of Wnt/beta-catenin signaling pathway in cancer cell lines. Analysis of its spatiotemporal expression in mouse embryos from E7.5 to E14 showed that Drapc1 is expressed during development of the extraembryonic structures, nervous system, vascular system and inner ear. In(More)
beta-Catenin is a multifunctional protein involved in both signalling by secreted factors of Wnt family and regulation of the cellular architecture. We show that beta-catenin stabilization in mouse midbrain-rhombomere 1 region leads to robust up-regulation of several Wnt signalling target genes, including Fgf8. Suggestive of direct transcriptional(More)
Conditional gene targeting strategies are progressively used to study gene function tissue-specifically and/or at a defined time period. Instrumental to all of these strategies is the generation of targeting vectors, and any methodology that would streamline the procedure would be highly beneficial. We describe a comprehensive transposition-based strategy(More)
β-catenin has well-established functions in cell growth and differentiation as part of the Wnt signaling pathway and in regulation of cellular adhesion with E-cadherin. Here we studied its significance in midbrain development by temporally controlled deletion of β-catenin allowing simultaneous analysis of complete (β-cat-null) and partial (β-cat-low)(More)
Affinity score is from human to mouse alignment (affinity of the weaker species is shown). Affinity score is from human to mouse alignment (affinity in the weaker species is shown). Affinity score is from human to mouse alignment (affinity of the weaker species is shown). Compare to Table S2 (predictions made using EEL). Predicted enhancer modules with two(More)
