Dissecting principles governing actin assembly using yeast extracts.

[wiskott-aldrich syndrome]

In this chapter, we describe recent protocols that we have developed to trigger actin assembly and actin-based motility in yeast cell extracts. Our method allows for the fast preparation of yeast extracts that are competent in dynamic assembly of distinct actin filament structures of biologically appropriate protein composition. Compared to previous extract-based systems using other eukaryotic cell types, yeast provides a unique advantage for combining reconstituted assays with the preparation of extracts from genetically modified yeast strains. We present a global strategy for dissecting the functions of individual proteins, where the activities of the proteins are analyzed in systems of variable complexity, ranging from simple mixtures of pure proteins to the full complexity of a cell's cytoplasm.
