SUMMARY PARAGRAPH for TEL02R-XC

TEL02R-XC, the X element core sequence on the right arm of chromosome II, spans 469 bp and contains an ARS consensus sequence and an Abf1p binding site consensus sequence.

Small conserved elements of ~475 bp, X element core sequences contain ARS consensus sequences and in most cases Abf1p binding sites, and are the only regions shared by all chromosome ends (2, 1). Between the ARS consensus sequence and the Abf1p binding site is a GC-rich region nearly identical to the meiosis-specific regulatory sequence URS1 (1). Possible functions include roles in chromosomal segregation, maintenance of chromosome stability, recombinational sequestering, or as a barrier to transcriptional silencing (1).

Other features of TEL02R, the right telomeric region of chromosome II, include X element combinatorial repeats TEL02R-XR and a short terminal stretch of telomeric repeats TEL02R-TR.
