TEL05L-XC, the X element core sequence on the left arm of chromosome V, is 194 bp long, contains an ARS consensus sequence, and spans dubious ORF YEL074W.

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 TEL05L, the left telomeric region of chromosome V, include a long Y' (Y'-L) element TEL05L-YP.
