Alternative definition : BIOCARTA: Telomerase is an enzyme that replicates the terminal sequences of eukaryotic
chromosomes, namely the telomeres. Cells that have an unlimited replicative capacity,
such as male germ cells and the majority of human cancers, have high levels of telomerase
activity. The level and frequency of telomerase activity in more than 85% of all cancers
highlights the critical role telomerase plays in tumor progression. Telomerase activation
is the most common general marker for a cancer cell to date making it an attractive
target for new cancer diagnostics and therapeutics. Human telomerase activity can
be reconstituted in vitro by the essential RNA subunit, hTERC, and the catalytic protein
component coded for by the hTERT gene. Both the human telomerase reverse transcriptase
gene (hTERT) and the telomerase RNA gene (hTERC) are controlled at least in part at
the transcriptional level. The hTERT gene is expressed at low levels in cancer cells
and is generally undetectable in normal cells. (This definition may be outdated -
