No DDRama at chromosome ends: TRF2 takes centre stage

Antonio Porro, Liuh-Yow Chen, Sascha Feuerhahn

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 ...

TERRA-Reinforced Association of LSD1 with MRE11 Promotes Processing of Uncapped Telomeres

Joachim Lingner, Antonio Porro, Sascha Feuerhahn

Telomeres protect chromosome ends from being recognized as sites of DNA damage. Upon telomere shortening or telomere uncapping induced by loss of telomeric repeat-binding factor 2 (TRF2), telomeres elicit a DNA-damage response leading to cellular senescenc ...

TERRA biogenesis, turnover and implications for function

Joachim Lingner, Antonio Porro, Sascha Feuerhahn, Andrea Bernardo Panza, Nahid Iglesias

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 ...

Molecular dissection of telomeric repeat-containing RNA biogenesis unveils the presence of distinct and multiple regulatory pathways

Joachim Lingner, Antonio Porro, Sascha Feuerhahn

Telomeres are transcribed into telomeric repeat-containing RNA (TERRA), large, heterogeneous, noncoding transcripts which form part of the telomeric heterochromatin. Despite a large number of functions that have been ascribed to TERRA, little is known abou ...
