Shelterin Complex at Telomeres: Implications in Ageing CIA
WebJustiça Federal da 2ª Região lança inédito portal para monitoramento de ações sobre saúde pública. Guilherme Calmon participa de Seminário sobre Subtração Internacional de … Shelterin has six subunits: TRF1, TRF2, POT1, RAP1, TIN2, and TPP1. They can operate in smaller subsets to regulate the length of or to protect telomeres. TRF1 (Telomere Repeat binding Factor 1): TRF1 is a homodimeric protein that binds to the double-stranded TTAGGG region of the telomere. TRF1 along with … See more Shelterin (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. In mammals and other vertebrates, … See more At least four factors contribute to telomere maintenance in most eukaryotes: telomerase, shelterin, TERRA and the CST Complex. Fission yeast ( Plants contain a … See more • TERRA (biology) • CST Complex See more There are two main DNA-damage-signaling pathways that shelterin represses: the ATR kinase pathway, blocked by POT1, and the ATM kinase pathway, blocked by TRF2. In the ATR kinase pathway, ATR and ATRIP sense the presence of single … See more TIN2 can localize to mitochondria where it promotes glycolysis. TIN2 loss in human cancer cells has resulted in reduced glycolysis and … See more WebOn the other hand, TRF1 and TRF2 are connected to TIN2 and RAP1, respectively. 51,54 It has been shown that TRF1 and TRF2 participate in DNA double-strand break repair at non-telomeric regions. 58 Both TRF1 and TRF2 regulate telomerase activity, but neither plays a role in regulating telomerase gene expression. 59 TRF1 suppresses telomerase ... nightwish oceanborn vinyl
