Faithful genome segregation depends on the functions of the eukaryotic centromere, which is characterized by the histone variant CENP-A. Gene replacement in human cells and fission yeast has now been used to show how CENP-A biochemically encodes centromere identity, as well as reveal an unexpected role for CENP-B in centromere function.
