Mitosis

Mitosis is the complex process in which duplicated chromosomes are condensed, segregated with the help of the mitotic spindle, and packaged in to daughter cell nuclei. Mitosis occurs in five stages: prophase, prometaphase, metaphase, anaphase and telophase.

    Assembly of the mitotic spindle requires timely separation of the centrosomes. Their movement apart is driven by the plus-end-directed kinesin Eg5. A new study demonstrates that the kinesin KIFC3 provides an opposing microtubule-based cohesive force that modulates centrosome separation and ensures accurate chromosome segregation.

    During mitosis, the kinetochore connects chromosomes to spindle microtubules and enables chromosome segregation. A genetic study in vertebrate cells demonstrates phosphorylation-regulated plasticity of kinetochore assembly and highlights the role of the centromere protein T in load-bearing kinetochore–microtubule attachment.

    Classical actin-dependent, integrin-mediated cell–matrix adhesions disassemble before mitotic rounding. Yet, to transmit positional information and facilitate daughter-cell separation, dividing cells maintain connections to the matrix. A previously unidentified class of actin-independent integrin adhesions may fulfil this task.
