Nature … WebOct 23, 2024 · Mammalian telomeres are TTAGGG repeats that mark chromosome ends. At each cell division, telomeres shorten due to the uncomplete replication of DNA ends. When telomere length shortens to a critical point, cells stop proliferating and enter a state known as replicative senescence (Campisi and d’Adda di Fagagna, 2007).

Telomerase is a cellular RNA-dependent DNA polymerase that serves to maintain the tandem arrays of telomeric TTAGGG repeats at eukaryotic chromosome ends (Morin, 1989; Blackburn and Greider, 1995).In human cells, the enzyme comprises a high molecular weight complex with a template-containing RNA subunit …
To establish global binding profiles of TRF1 and TRF2 (collectively named the TRF proteins), we performed a ChIP-Seq analysis with one antibody specific for TRF1 and two antibodies specific for TRF2 (one monoclonal or TRF2m, one polyclonal or TRF2p).
