In Vitro Biochemical Characterization of Cytokinesis Actin-Binding Proteins

  • Protocol

Part of the book series: Methods in Molecular Biology ((MIMB,volume 1369))

Abstract

Characterizing the biochemical and biophysical properties of purified proteins is critical to understand the underlying molecular mechanisms that facilitate complicated cellular processes such as cytokinesis. Here we outline in vitro assays to investigate the effects of cytokinesis actin-binding proteins on actin filament dynamics and organization. We describe (1) multicolor single-molecule TIRF microscopy actin assembly assays, (2) “bulk” pyrene actin assembly/disassembly assays, and (3) “bulk” sedimentation actin filament binding and bundling assays.
