Sequence Annotation Notes
2004-10-12The orientation of this centromere was reversed (from Watson to Crick) to accommodate annotation of the centromeric DNA elements CDEI, CDEII, and CDEIII based on Wieland et al. and Espelin et al.

Mapping Notes
1996-09-21Edition 13: There are three conserved sequence elements in the centromere that are sufficient for mitotic and meiotic segregation. CDEI (8bp) is required for mitotic segregation; although most assays indicate it is dispensable for meiotic chromosome segregation, it is needed for meiosis I plasmid disjunction. CDEII (78-86 bp A-T rich region) is specifically required for meiosis I disjunction. CDEIII (25 bp) is essential for both mitotic and meiotic segregation.
