Responses of chromosome segregation machinery to mechanical perturbations
For genome stability, the proper segregation of chromosomes is required. The exquisite process of chromosome segregation has charmed a lot of cell- and molecular biologists into watching what happens inside a mitotic cell and how each molecule contributes to this process for the accomplishment of accurate cell division1. The process to partition the duplicated genome to the daughter cells in ea...
متن کاملA multidomain hub anchors the chromosome segregation and chemotactic machinery to the bacterial pole.
The cell poles constitute key subcellular domains that are often critical for motility, chemotaxis, and chromosome segregation in rod-shaped bacteria. However, in nearly all rods, the processes that underlie the formation, recognition, and perpetuation of the polar domains are largely unknown. Here, in Vibrio cholerae, we identified HubP (hub of the pole), a polar transmembrane protein conserve...
متن کاملComplex polar machinery required for proper chromosome segregation in vegetative and sporulating cells of Bacillus subtilis
Chromosome segregation is an essential process of cell multiplication. In prokaryotes, segregation starts with the newly replicated sister origins of replication, oriCs, which move apart to defined positions in the cell. We have developed a genetic screen to identify mutants defective in placement of oriC during spore development in the Gram-positive bacterium Bacillus subtilis. In addition to ...
متن کاملDriving chromosome segregation: lessons from the human and Drosophila centromere-kinetochore machinery.
The kinetochore is a complex molecular machine that serves as the interface between sister chromatids and the mitotic spindle. The kinetochore assembles at a particular chromosomal locus, the centromere, which is essential to maintain genomic stability during cell division. The kinetochore is a macromolecular puzzle of subcomplexes assembled in a hierarchical manner and fulfils three main funct...
متن کاملTrypanosome outer kinetochore proteins suggest conservation of chromosome segregation machinery across eukaryotes
Kinetochores are multiprotein complexes that couple eukaryotic chromosomes to the mitotic spindle to ensure proper segregation. The model for kinetochore assembly is conserved between humans and yeast, and homologues of several components are widely distributed in eukaryotes, but key components are absent in some lineages. The recent discovery in a lineage of protozoa called kinetoplastids of u...
