SMCHD1 promotes ATM-dependent DNA damage signaling and repair of uncapped telomeres

Joachim Lingner, Wareed Ahmed, Verena Pfeiffer, Marianna Feretzaki, Aleksandra Vancevska

Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (SMCHD1) has been implicated in X-chromosome inactivation, imprinting, and DNA damage repair, and mutations in SMCHD1 can cause facioscapulohumeral muscular dystrophy. More re ...

The telomeric DNA damage response occurs in the absence of chromatin decompaction

Joachim Lingner, Suliana Manley, Verena Pfeiffer, Aleksandra Vancevska, Kyle Michael Douglass

Telomeres are specialized nucleoprotein structures that protect chromosome ends from DNA damage response (DDR) and DNA rearrangements. The telomeric shelterin protein TRF2 suppresses the DDR, and this function has been attributed to its abilities to trigge ...

Nanoscale Spatial Organization of Chromatin in its Cellular Context, from Telomeres to Hox

Denis Duboule, Joachim Lingner, Suliana Manley, Kyle Michael Douglass, Aleksandr Benke, Verena Pfeiffer, Pierre Raymond Fabre, Aleksandra Vancevska

The THO complex component Thp2 counteracts telomeric R-loops and telomere shortening

Joachim Lingner, Larissa Grolimund, Verena Pfeiffer, Jérôme Crittin

Telomere maintenance by the conventional DNA replication machinery and telomerase is assisted by specialized DNA helicases, nucleases and telomere binding proteins. Here, we identify the THO components at telomeres and define critical roles of this complex ...

Replication of Telomeres and the Regulation of Telomerase

Joachim Lingner, Verena Pfeiffer

Telomeres are the physical ends of eukaryotic chromosomes. They protect chromosome ends from DNA degradation, recombination, and DNA end fusions, and they are important for nuclear architecture. Telomeres provide a mechanism for their replication by semico ...

TERRA Promotes Telomere Shortening through Exonuclease 1-Mediated Resection of Chromosome Ends

Joachim Lingner, Verena Pfeiffer

The long noncoding telomeric repeat containing RNA (TERRA) is expressed at chromosome ends. TERRA upregulation upon experimental manipulation or in ICF (immunodeficiency, centromeric instability, facial anomalies) patients correlates with short telomeres. ...
