Summary: Predicted to enable DNA binding activity; metal ion binding activity; and telomerase activity. Involved in telomere maintenance via telomerase. Predicted to be located in chromosome, telomeric region and nucleus. Used to study cancer. Human ortholog(s) of this gene implicated in several diseases, including autosomal dominant dyskeratosis congenita 2; carcinoma (multiple); gastrointestinal stromal tumor; leukemia (multiple); and melanoma (multiple). Orthologous to human TERT (telomerase reverse transcriptase). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The results establish that null mutation in trt-1 improves survival and attenuates damage to the DAergic system.
Title: Null allele mutants of trt-1, the catalytic subunit of telomerase in Caenorhabditis elegans, are less sensitive to Mn-induced toxicity and DAergic degeneration.
Telomerase may be required to prevent or repair sporadic telomere truncations that are unrelated to the typical 'end-replication' problems.
Title: High incidence of rapid telomere loss in telomerase-deficient Caenorhabditis elegans.
trt-1 is the Caenorhabditis elegans catalytic subunit of telomerase
Title: trt-1 is the Caenorhabditis elegans catalytic subunit of telomerase.
