A Polyadenylation-Dependent 3′ End Maturation Pathway Is Required for the Synthesis of the Human Telomerase RNA

Abstract excerpt

Telomere maintenance by the telomerase reverse transcriptase requires a noncoding RNA subunit that acts as a template for the synthesis of telomeric repeats. In humans, the telomerase RNA (hTR) is a non-polyadenylated transcript produced from an independent transcriptional unit. As yet, the mechanism and factors responsible for hTR 3' end processing have remained largely unknown. Here, we show that hTR is matured...
