Telomerase is a specialized reverse transcriptase containing an intrinsic telomerase RNA (TR) which provides the template for telomeric DNA synthesis. Distinct from conventional reverse transcriptases, telomerase has evolved a unique TR-binding domain (TRBD) in the catalytic telomerase reverse transcriptase (TERT) protein, integral for ribonucleoprotein(More)
Telomerase is a large ribonucleoprotein complex minimally composed of a catalytic telomerase reverse transcriptase (TERT) and an RNA component (TR) that provides the template for telomeric DNA synthesis. However, it remains unclear how TERT and TR assemble into a functional telomerase. Here we report the crystal structure of the conserved regions 4 and 5(More)
Telomerase RNA (TER) is an essential component of the telomerase ribonucleoprotein complex. The mechanism for TER 3'-end processing is highly divergent among different organisms. Here we report a unique spliceosome-mediated TER 3'-end cleavage mechanism in Neurospora crassa that is distinct from that found specifically in the fission yeast(More)
Telomerase is a unique reverse transcriptase that replicates the telomeric DNA at most eukaryotic chromosomal ends. The telomerase consists of the catalytic protein subunit TERT and the RNA component TR that provides the template for telomeric DNA synthesis. In vitro reconstitution of telomerase core components in large quantity is the prerequisite to(More)
