The lengths of human telomeres, which protect chromosome ends from degradation and end fusions(1,2), are crucial determinants of cell lifespan(3). During embryogenesis and in cancer, the telomerase enzyme counteracts telomeric DNA shortening. As shown in c ...
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 ...
Paxos is probably the most popular state machine replication protocol. Two optimizations that can greatly improve its performance are batching and pipelining. However, tuning these two optimizations to achieve high-throughput can be challenging, as their e ...
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 ...
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 ...
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 ...
Telomerase is required for telomere maintenance and is responsible for the immortal phenotype of cancer cells. How telomerase is assembled and reaches telomeres in the context of nuclear architecture is not understood. Recently, the telomerase RNA subunit ...
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 ...
Telomerase is the ribonucleoprotein enzyme that elongates telomeres to counteract telomere shortening. The core enzyme consists of a reverse transcriptase protein subunit and an RNA subunit. The RNA subunit contains a short region that is used as a templat ...
Telomerase enables telomere length homeostasis, exhibiting increasing preference for telomeres as their lengths decline. This regulation involves telomere repeat-bound Rap1, which provides a length-dependent negative feedback mechanism, and the Tel1 and Me ...
