SUMMARY PARAGRAPH for TEL10R-XR

TEL10R-XR, the X element combinatorial repeat region on the right arm of chromosome X, spans 300 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 TEL10R, the right telomeric region of chromosome X, include an X element core sequence TEL10R-XC, and a short terminal stretch of telomeric repeats TEL10R-TR.
