SUMMARY PARAGRAPH for TEL15L-XR

TEL15L-XR, the X element combinatorial repeat region on the left arm of chromosome XV, spans 270 bp and contains repeats of the D, C, B and A types, as well as Tbf1p binding sites.

Formerly known as subtelomeric repeats or STRs, X element combinatorial repeats are generally between 250 and 300 bp long and are located between the X element core sequence and the telomeric end (1). X element combinatorial repeats are usually present as a combination of one or more of several types of smaller elements designated D, C, B, or A, with D types being most proximal to the centromere, followed by C types and so on (2). Most X element combinatorial repeat regions contain Tbf1p binding sites, and possible functions include a role in telomerase-independent telomere maintenance via recombination or as a barrier against transcriptional silencing (2).

Other features of TEL15L, the left telomeric region of chromosome XV, include an X element core sequence TEL15L-XC, and a terminal stretch of telomeric repeats TEL15L-TR.
