== Function ==
[https://www.uniprot.org/uniprot/TERT_TETTS TERT_TETTS] Catalytic component of telomerase, an essential ribonucleoprotein enzyme that copies new telomeric repeats onto chromosome ends by repetitively synthesizing the short telomere-repeat sequence 5'-TTGGGG-3' using an RNA template component TER (PubMed:10944124, PubMed:15696174, PubMed:17322903, PubMed:20713447, PubMed:16462747). TERT is a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme (PubMed:10944124, PubMed:15696174, PubMed:17322903, PubMed:20713447, PubMed:16462747).<ref>PMID:10944124</ref> <ref>PMID:15696174</ref> <ref>PMID:16462747</ref> <ref>PMID:17322903</ref> <ref>PMID:20713447</ref>
