Coordinated events of nuclear assembly

Curr Opin Cell Biol. 2017 Jun;46:39-45. doi: 10.1016/ Epub 2017 Feb 9.


Each time a metazoan cell undergoes open mitosis, the nucleus is dismantled in order to partition DNA content to the daughter cells. After chromosomes separate, changes at the chromatin surface usher in reestablishment of nuclear architecture. Proteins destined for the nuclear envelope are attracted to chromatin and concomitantly recruit membrane. As nuclear envelope and protein constituents spread to coat chromatin, distinct regions emerge-some rich in rapid pore formation, others occupied by microtubules that remain attached to kinetochores. Microtubule connections present physical barriers that must be remodeled in order for the nuclear envelope to seal. Regions of the nascent nuclear envelope that are initially characterized by contrasting repertoires of nuclear envelope proteins rapidly coalesce as nuclei expand and enter interphase.
