Human RNA polymerase (Pol) III-transcribed genes are thought to share a simple termination signal constituted by four or more consecutive thymidine residues in the coding DNA strand, just downstream of the RNA 3'-end sequence. We found that a large set of ...
Telomeres are heterochromatic structures at the ends of eukaryotic chromosomes. As other heterochromatin regions, telomeres are transcribed, from the subtelomeric region towards chromosome ends into the long non-coding RNA TERRA. Telomere transcription is ...
Telomeres, the physical ends of eukaryotes chromosomes are transcribed into telomeric repeat containing RNA (TERRA), a large non-coding RNA of unknown function, which forms an integral part of telomeric heterochromatin. TERRA molecules resemble in sequence ...
Telomeres, the physical ends of eukaryotic chromosomes, consist of tandem arrays of short DNA repeats and a large set of specialized proteins. A recent analysis has identified telomeric repeat-containing RNA ( TERRA), a large non-coding RNA in animals and ...
The ends of linear eukaryotic chromosomes, telomeres, distinguish natural chromosome ends from DNA double stranded breaks and thus promote genome stability. Telomeres comprise a repetitive DNA skeleton, which is wrapped in specific protein complexes. Recen ...
Antisense oligonucleotides have been used to study the structure and function of small nuclear ribonucleoprotein (snRNP) complexes and were adapted and modified for the purification of a variety of RNPs. We describe methods for recombinant expression and r ...
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 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, the DNA-protein complexes located at the end of linear eukaryotic chromosomes, are essential for chromosome stability. Until now, telomeres have been considered to be transcriptionally silent. We demonstrate that mammalian telomeres are transcri ...
The human EST1A/SMG6 polypeptide physically interacts with the chromosome end replication enzyme telomerase. In an attempt to better understand hEST1A function, we have started to dissect the molecular interactions between hEST1A and telomerase. Here, we d ...
