Summary |
Accurate chromosome segregation requires centromeres (CENs), the chromosomal sites where kinetochores form, to bridge DNA and attach to microtubules. In contrast to most eukaryotes, Saccharomyces cerevisiae possesses sequence-defined point centromeres. Chromatin immunoprecipitation followed by sequencing (ChIP-Seq) of four kinetochore components reveals regions of overlapping, extra-centromeric protein localization upon overproduction of the centromeric histone, Cse4 (CENP-A or CenH3). These identified sequences enhance proper plasmid and chromosome segregation, and are termed Centromere-like Regions (CLRs). CLRs form in close proximity to S. cerevisiae CENs and share characteristics typical of point and regional centromeres. CLR sequences are conserved among related budding yeasts, suggesting a role in vivo. These studies provide new insights into the origin and evolution of centromeres.
