General description
Telomerase reverse transcriptase (EC 2.7.7.49; UniProt O14746; also known as hEST2, hTRT, Telomerase-associated protein 2, Telomerase catalytic subunit, TP2) is encoded by the TERT (also known as CMM9, DKCA2, DKCB4, EST2, PFBMFT1, TCS1, TRT) gene (Gene ID 7015) in human. Telomerase reverse transcriptase (TERT) is the catalytic subunit of the telomerase responsible for adding TTAGGG repeats to the chromosome telomere ends. Cells with low or no telomerase expression lose telomere repeats during cell division, eventually resulting in cellular senescence. Most cancer cells, germ cells and embryonic stem cells express high levels of telomerase, thus contributing to pluripotency and immortality. In addition to its telomere maintenance function, telomerase also has a pro-survival role in cellular resistance against DNA damage and ensuing apoptosis. Most cancer cells are highly proliferative and express high levels of nuclear telomerase activity. Studies show that TERT shuttles from the nucleus into mitochondria upon oxidative stress induction in cancer cells. TERT mitochondrial localization helps prevent nuclear DNA damage by decreasing mitochondrial reactive oxygen species (ROS), accounting for high stress resistance especially among the cancer stem cells (CSCs) population. Following exposure to H2O2 or gamma-irradiation, cancer cells capable of excluding TERT from the nucleus display little or no DNA damage, while TERT nuclear retainment results in high DNA damage.
Specificity
This polyclonal antibody targets a sequence toward the end of the C-terminal extension (CTE) region present in spliced isoforms 1 and 3, but not in isoforms 2 and 4 of hTERT reported by UniProt (O14746).
Immunogen
Epitope: C-terminal extension (CTE).
KLH-conjugated linear peptide corresponding to a sequence from the C-terminal extension (CTE) region of human TERT.
Application
Immunocytochemistry Analysis: An 1:200 dilution from a representative lot detected TERT in A431, HeLa, HUVEC and NIH/3T3 cells.
Immunohistochemistry Analysis: An 1:250 dilution from a representative lot detected TERT in human cerebral cortex, human pancreas, and rat testis tissue sections.

Human telomerase reverse transcriptase (hTERT) plays an extremely important role in cancer initiation and development, including colorectal cancer (CRC). However, the precise upstream regulatory mechanisms of hTERT in different cancer types remain poorly understood. Here, we uncovered the candidate transcriptional
