WebShelterin-related complexes are also found at telomeres in other eukaryotes. POT1-like proteins are present in nearly all eukaryotes (de Lange 2001), a TRF1/2 like protein is found in fission yeast and in trypanosomes (Cooper et al. 1998; Sfeir et al. 2005), and Rap1 is present in fungi (Shore 1994; Chikashige and Hiraoka 2001; Kanoh and Ishikawa 2001). WebFor more than a decade, it has been known that mammalian cells use shelterin to protect chromosome ends. Much progress has been made on the mechanism by which shelterin prevents telomeres from inadvertently activating DNA damage signaling and double-strand break (DSB) repair pathways.

WebShelterin (also called telosome) is a protein complex known to protect telomeres in many eukaryotes from DNA repair mechanisms, as well as to regulate telomerase activity.
