SUMMARY PARAGRAPH for TEL09L-XR

TEL09L-XR, the X element combinatorial repeat region on the left arm of chromosome IX, spans 372 bp and contains a repeat of the D type with a group I mitochondrial bI4 intron insertion.

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 TEL09L, the left telomeric region of chromosome IX, include an X element core sequence TEL09L-XC, a long Y' (Y'-L) element TEL09L-YP and a short terminal stretch of telomeric repeats TEL09L-TR.
