Human telomerase is a ribonucleoprotein that is minimally comprised of protein (hTERT) and RNA (hTR) components. We have applied single-molecule fluorescence two-color coincidence detection to characterize complex formation between fluorophore-labeled components in solution. By systematic labeling and in vitro assembly of hTERT, hTR and telomerase's DNA substrate, we have established that catalytically functional human telomerase comprises a stable hTERT:hTR:substrate interaction in a 1:1:1… CONTINUE READING
