Mechanisms of nuclear actin in chromatin-remodeling complexes.

Highlights: [•] Chromatin-modifying complexes are a well-defined system for studying nuclear actin. [•] In contrast to cytosolic actin, nuclear actin in INO80 complex functions as a monomer. [•] Nuclear actin forms modules with actin-related proteins to interact with chromatin. [•] New insights into nuclear actin suggest a paradigm distinct from cytosolic actin. [Copyright &y& Elsevier]
