Plasmodium falciparum GBP2 Is a Telomere-Associated Protein That Binds to G-Quadruplex DNA and RNA

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
In the early-diverging protozoan parasite Plasmodium, few telomere-binding proteins have been identified and several are unique. Plasmodium telomeres, like those of most eukaryotes, contain guanine-rich repeats that can form G-quadruplex structures.

Non-canonical roles of canonical telomere binding proteins in cancers [PDF]

open access: yesCellular and Molecular Life Sciences, 2021
AbstractReactivation of telomerase is a major hallmark observed in 90% of all cancers. Yet paradoxically, enhanced telomerase activity does not correlate with telomere length and cancers often possess short telomeres; suggestive of supplementary non-canonical roles that telomerase might play in the development of cancer.

TZAP overexpression induces telomere dysfunction and ALT-like activity in ATRX/DAXX-deficient cells

open access: yesiScience, 2023
Summary: The appropriate regulation of telomere length homeostasis is crucial for the maintenance of genome integrity. The telomere-binding protein TZAP has been suggested to regulate telomere length by promoting t-circle and c-circle excisions through ...

TRF2 controls telomeric nucleosome organization in a cell cycle phase-dependent manner [PDF]

open access: yes, 2012
Mammalian telomeres stabilize chromosome ends as a result of their assembly into a peculiar form of chromatin comprising a complex of non-histone proteins named shelterin.

Sir4 Deficiency Reverses Cell Senescence by Sub-Telomere Recombination

open access: yesCells, 2021
Telomere shortening results in cellular senescence and the regulatory mechanisms remain unclear. Here, we report that the sub-telomere regions facilitate telomere lengthening by homologous recombination, thereby attenuating senescence in yeast ...

The TERB1 MYB domain suppresses telomere erosion in meiotic prophase I

open access: yesCell Reports, 2022
Summary: The meiosis-specific telomere-binding protein TERB1 anchors telomeres to the nuclear envelope and drives chromosome movements for the pairing of homologous chromosomes.

TRF1 and TRF2 binding to telomeres is modulated by nucleosomal organization [PDF]

open access: yes, 2015
The ends of eukaryotic chromosomes need to be protected from the activation of a DNA damage response that leads the cell to replicative senescence or apoptosis.

The Ku subunit of telomerase binds Sir4 to recruit telomerase to lengthen telomeres in S. cerevisiae

open access: yeseLife, 2015
In Saccharomyces cerevisiae and in humans, the telomerase RNA subunit is bound by Ku, a ring-shaped protein heterodimer best known for its function in DNA repair. Ku binding to yeast telomerase RNA promotes telomere lengthening and telomerase recruitment

Emerging roles of telomeric chromatin alterations in cancer [PDF]

open access: yes, 2019
Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...
