Control of telomere length by the human telomeric protein TRF1.
Nature - 20 Feb 1997
van Steensel B, de Lange T
Abstract excerpt
Human telomeres, the nucleoprotein complexes at chromosome ends, consist of tandem arrays of TTAGGG repeats bound to specific proteins. In normal human cells, telomeres shorten with successive cell divisions, probably due to the terminal sequence loss that accompanies DNA replication. In tumours and immortalized cells, this decline is halted through the activation of telomerase, a reverse transcriptase that...
