The enzyme consists of a protein … WebJun 10, 2024 · Background: Cancer cells become immortalized through telomere maintenance mechanisms, such as telomerase reverse transcriptase (TERT) activation. In addition to maintaining telomere length, TERT activates manifold cell survival signaling pathways. However, telomerase-associated gene signatures in cancer remain elusive.
WebTelomerase reverse transcriptase (TERT) is a gene located on chromosome 5p15.33, and encodes for the catalytic subunit of telomerase [1]. Telomerase is an enzyme whose mechanism of action consists on the addition of nucleotides to telomeres. Telomerase is a ribonucleoprotein polymerase that maintains telomere ends by addition of the telomere repeat TTAGGG. The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component that serves as a template for the telomere repeat. … See more Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most … See more The hTERT gene, located on chromosome 5, consists of 16 exons and 15 introns spanning 35 kb.
