Kinetochore assembly throughout the cell cycle

The kinetochore plays an essential role in facilitating chromosome segregation during cell division. This massive protein complex assembles onto the centromere of chromosomes and enables their attachment to spindle microtubules during mitosis. The kinetochore also functions as a signaling hub to regulate cell cycle progression, and is crucial to ensuring the fidelity of chromosome segregation. Despite the fact that kinetochores are large and robust molecular assemblies, they are also highly dynamic structures that undergo structural and organizational changes throughout the cell cycle. This review will highlight our current understanding of kinetochore structure and function, focusing on the dynamic processes that underlie kinetochore assembly.

Automated summary

The kinetochore plays a crucial role in facilitating chromosome segregation during cell division by attaching chromosomes to spindle microtubules. It also acts as a signaling hub to regulate cell cycle progression and ensures the accuracy of chromosome segregation. Despite being large and robust molecular assemblies, kinetochores undergo dynamic structural and organizational changes throughout the cell cycle.
