Which protein complexes recognize centromeric (CEN) DNA in yeast?
The Schizosaccharomyces pombe centromere-linked genes, LYS1 and CYH1 on chromosome I and TPS13 and RAN1 on chromosome II, have been isolated. In budding yeast, as well as in other eukaryotes, the Cse4 histone variant (known in vertebrates as CENP-A) is believed to substitute for histone H3 at the centromeric nucleosome.
