Actin filament assembly is a tightly regulated process that functions in many aspects of cell physiology. Members of the Ena/VASP (Drosophila Enabled/vasodilator-stimulated phosphoprotein) family are key players in regulating actin filament assembly, in many cases through their association with binding partners that display a particular proline-rich motif,(More)
The zyxin family of proteins function as cytoskeletal regulators in adhesion, actin assembly, and cell motility. Though fibroblasts derived from zyxin-null mice show striking defects in motility and response to mechanical stimuli, the mice are viable and fertile. In Drosophila melanogaster, the family is represented by a single homologue, Zyx102. To study(More)
Adherens junctions, which are cadherin-mediated junctions between cells, and focal adhesions, which are integrin-mediated junctions between cells and the extracellular matrix, are protein complexes that link the actin cytoskeleton to the plasma membrane and, in turn, to the extracellular environment. Zyxin is a LIM domain protein that is found in vertebrate(More)
