The dickkopf (dkk) gene family encodes secreted antagonists of Wnt signalling proteins, which have important functions in the control of cell fate, proliferation, and cell polarity during development. Here, we report the isolation, from a regeneration-specific signal peptide screen, of a novel dickkopf gene from the fresh water cnidarian Hydra. Comparative(More)
Members of the BTB-kelch superfamily play important roles during fundamental cellular processes, such as the regulation of cell morphology, migration, and gene expression. The BTB-kelch protein LZTR-1 is deleted in the majority of DiGeorge syndrome patients and is believed to act as a transcriptional regulator. However, functional and expression profiling(More)
Sprouting and invasive migration of endothelial cells are important steps of the angiogenic cascade. Vascular endothelial growth factor (VEGF) induces angiogenesis by activating intracellular signal transduction cascades, which regulate endothelial cell morphology and function. BTB-kelch proteins are intracellular proteins that control cellular architecture(More)
