Graphical abstract
Schematic representation of a mitotic spindle and the organization of core proteins of inner and outer kinetochore.
Public summary
■ Centromere is a vital macromolecular machinery for cell renewal quality control.
■ CENP-A nucleosome is the hallmark and foundation for centromere and kinetochore assembly.
■ Centromere and kinetochore core complex CCAN undergoes dynamic remodeling from CENP-A nucleosome-elicited loading to DNA-centric gripping upon assembly.
■ The excitement and challenge ahead are to illuminate the spatiotemporal characteristics of CCAN assembly in situ at atomic resolution.
