TEL06L-Yp, the short Y' (Y'-S) element on the left arm of chromosome VI, contains a region of 36-bp repeats and five uncharacterized ORFs (YFL064C, YFL065C, YFL066C, YFL067W and YFL068W).

The Y' element is a repetitive sequence found in many but not all subtelomeric regions next to the telomeric repeats, or adjacent X element combinatorial repeats, either as a single copy or tandem repeat of two to four copies(2, 3). Two main types of Y' elements are known, Y'-L and Y'-S, and any particular array will consist of only one type, not a combination of both (1). Y' elements contain helicase-encoding ORFs which are expressed only during meiosis and in telomerase-deficient cells (1). Possible functions include rescue of telomeres when the telomeric repeats are no longer present and a role in telomere maintenance during meiosis (1).

Other features of TEL06L, the left telomeric region of chromosome VI, include an X element core sequence TEL06L-XC, a region of X element combinatorial repeats TEL06L-XR, and a stretch of telomeric repeats TEL06L-TR.
