Chromosome Segregation in Closed Mitosis Under an Excess of Nuclear Envelope
Biology of the Cell, Volume 117, Issue 5, May 2025.This study investigated the impact of Nem1‐Spo7/lipin‐mediated nuclear envelope (NE) size regulation during closed mitosis in Saccharomyces cerevisiae. Nem1 depletion resulted in persistent chromatin protrusions, particularly at the rDNA locus, leading to lagging chromosome XII's right arm sisters during late anaphase.
