The telomeric shelterin component TPP1 has critical functions in telomeric protein complex assembly and telomerase recruitment and regulation. Here we identify USP7 as a novel interacting protein of the oligonucleotide/oligosaccharide-binding fold of TPP1, ...
Long noncoding telomeric repeat-containing RNAs TERRAs - are transcribed in a regulated manner from telomeres throughout eukaryotes. TERRA molecules consist of chromosome end-specific subtelomeric sequences and telomeric repeats at their 3' ends. Recent wo ...
Recruitment to telomeres is a pivotal step in the function and regulation of human telomerase. Impaired telomerase function can lead to premature organismal aging, development of cancer and multisystem disorders such as dyskeratosis congenita. Telomerase a ...
Telomeres protect linear ends of eukaryotic chromosomes by preventing chromosomal end-to-end fusions and telomere attrition. They consist of repetitive DNA sequences, telomeric repeat containing RNAs (TERRAs) and proteins. Telomeres play a crucial role in ...
Telomeres, the physical ends of eukaryotic chromosomes, are transcribed into telomeric repeat-containing RNA (TERRA), a large non-coding RNA, which forms an integral part of telomeric heterochromatin. In vitro, naked TERRA molecules are efficient inhibitor ...
Telomere composition changes during tumourigenesis, aging and in telomere syndromes in a poorly defined manner. Here we develop a quantitative telomeric chromatin isolation protocol (QTIP) for human cells, in which chromatin is cross-linked, immunopurified ...
Telomerase is responsible for the immortal phenotype of cancer cells and telomerase inhibition may specifically target cancer cell proliferation. Ligands able to selectively bind to G-quadruplex telomeric DNA have been considered as telomerase inhibitors b ...
Telomeres are the DNA/RNA/protein structures at the end of linear eukaryotic chromosomes, which protect them against the DNA damage repair machinery, preventing chromosome end-to-end fusions and aberrant recombination. Moreover, telomeres compensate for th ...
Telomeres are nucleoprotein structures capping the natural termini of eukaryotic linear chromosomes. Telomeres possess an inherent ability to circumvent the activation of a full-blown DNA damage response (DDR), and hence fusion reactions, by limiting inapp ...
Recruitment to telomeres is a pivotal step in the function and regulation of human telomerase; however, the molecular basis for recruitment is not known. Here, we have directly investigated the process of telomerase recruitment via fluorescence in situ hyb ...
