Mechanism of dominant-negative telomerase function.

Abstract excerpt

Human telomerase uses its integral core components, hTR and hTERT, to maintain telomeres in many cell types. Expression of a dominant-negative mutant of the catalytic subunit of telomerase, DN-hTERT, has been shown to cause telomere shortening and ultimately cell death in a number of tumor-derived cell lines. However, the mechanism of dominant-negative hTERT function and its fate inside the cell are still...
