Complex interaction network revealed by mutation of human telomerase 'insertion in fingers' and essential N-terminal domains and the telomere protein TPP1.

Abstract excerpt

In the majority of human cancer cells, cellular immortalization depends on the maintenance of telomere length by telomerase. An essential step required for telomerase function is its recruitment to telomeres, which is regulated by the interaction of the telomere protein, TPP1, with the telomerase essential N-terminal (TEN) domain of the human telomerase reverse transcriptase, hTERT. We previously reported that...
