Abstract
A human subtelomeric repeat (designated as the HST repeat) has been isolated and characterized from a yeast artificial chromosome containing one human telomere. This repeat is located immediately adjacent to the telomeric T2AG3 repeats at the extreme termini of the human chromosomes. The DNA sequence of 3.6 kb of the HST repeat has been determined. The HST repeat spans over 3.6 kb in length, and contains one evolutionarily conserved CpG-rich region. The copy number of the HST repeat varies among telomeres. Genomic hybridization experiments suggest that the HST repeat consists of two distinct segments, and the distal portions of the HST repeat are also distributed elsewhere in the genome. In HeLa cells, the HST repeat sequence appears to be transcribed into a 6 kb polyadenylated RNA and a variety of non-polyadenylated RNA species.Entities:
