Centromere proteins and chromosome inheritance: a complex affair

Abstract

Centromeres and the associated kinetochores are involved in essential aspects of chromosome transmission. Recent advances have included the identification and understanding of proteins that have a pivotal role in centromere structure, kinetochore formation, and the coordination of chromosome inheritance with the cell cycle in several organisms. A picture is beginning to emerge of the centromere-kinetechore as a complex and dynamic structure with conservation of function at the protein level across diverse species.
