Development of cancer chemotherapeutics directed against the reverse-transcriptase domain of telomerase has been challenging, perhaps because the enzyme needs only low activity to maintain telomeres. | Development of cancer chemotherapeutics directed against the reverse-transcriptase domain of telomerase has been challenging, perhaps because the enzyme needs only low activity to maintain telomeres. | ||
Because the TEN domain is essential for telomerase activity and its structure seems to be conserved trough evolution, this portion of TERT is a potential new target for antitelomerase compounds. | Because the TEN domain is essential for telomerase activity and its structure seems to be conserved trough evolution, this portion of TERT is a potential new target for antitelomerase compounds. | ||
