Telomerases PDF

This book is a comprehensive and up-to-date review and evaluation of the contemporary status of telomerase research. Chapters in this volume cover the basic structure, mechanisms, and diversity of the essential and regulatory subunits of telomerase. Other topics include telomerase biogenesis, transcriptional and post-translational regulation, off-telomere functions of telomerase and the role of telomerase in cellular senescence, aging and cancer. Its relationship to retrotransposons, a class of mobile genetic elements that shares similarities with telomerase and serves as telomeres in selected organisms, are also reviewed.

Telomerase is repressed in most normal cells, allowing telomere length to gradually decrease and preventing uncontrolled proliferation. In tissues that have a high turnover throughout life, such as blood and gut, telomerase can be transiently upregulated in progenitor cells to maintain telomeres and enable controlled, self-limited proliferation to replace cells lost through natural processes.

Telomerase: biochemical considerations for … The catalytic subunit of all telomerases identified contains a domain with motifs homologous to the conserved RT motifs universally present in reverse transcriptases. The finding that mutations in key residues affecting HIV RT catalytic activity similarly disrupted telomerase activity demonstrates that the telomerase RT domain is also

Telomerase, also called terminal transferase, is a ribonucleoprotein that adds a species-dependent telomere repeat sequence to the 3' end of telomeres. Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is ...
