After mitosis, the nucleus must be rebuilt and chromatin decondensed to permit interphase genomic functions, but decondensation mechanisms are poorly understood. Now, the traditional cytoskeletal protein actin is shown to form transient nuclear filaments that are required for chromatin decondensation and nuclear expansion at mitotic exit.
