Definition / general
  • A ribonucleoprotein multisubunit enzyme complex that functions as a specialized reverse transcriptase, to synthesize telomeric repeats (TTAGGG) to the 3 ends of human chromosomes
  • Components of telomerase: RNA template, telomerase associated protein, human telomerase reverse transcriptase (hTERT)
  • RNA template and telomerase associated protein are expressed ubiquitously
  • hTERT protein expression is highly regulated, generally correlates with telomerase activity; reexpression correlates with laryngeal carcinogenesis (Mod Pathol 2005;18:406)
  • hTERT is a nuclear stain
