Human Telomerase Reverse Transcriptase (hTERT)

Human Telomerase Reverse Transcriptase (hTERT) is an essential enzyme that helps maintain the protective caps at the ends of chromosomes, known as telomeres. These telomeres shorten as cells divide, which contributes to aging and limits the lifespan of cells. hTERT is crucial because it adds DNA sequences to the telomeres, allowing cells to divide longer and maintain their function. This enzyme is often active in stem cells and cancer cells, which can lead to uncontrolled growth. Understanding hTERT is important in research on aging, cancer, and regenerative medicine.
