TEL03L-XC, the X element core sequence on the left arm of chromosome III, spans 458 bp and contains an ARS consensus sequence, and an Abf1p binding site.

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 TEL03L, the left telomeric region of chromosome III, include X element combinatorial repeats TEL03L-XR, and a short terminal stretch of telomeric repeats TEL03L-TR.
