What are they? Telomeres are the natural tips of chromosomes. They consist of tandem arrays of simple G-rich repetitive DNA sequences that are complexed with proteins. The fundamental tools for keeping telomeres healthy are amazingly similar in both single cell eukaryotes, such as yeast and ciliat...
But what are they in the first place? Telomeres are protective proteins found at the ends of chromosomes. They protect the ends of chromosomes the same way plastic caps protect the ends of shoe laces. Without them, the DNA strands become damaged and unable to function properly. See alsoHealth...

Telomeres are specialized chromatin domains located at the ends of chromosomes. They are involved in chromosome replication, stability and localization in the nucleus. In addition to these functions, recent work suggests that telomeres are involved in such superficially diverse cellular phenomena as ...
[206]. InArabidopsis, there are other proteins containing Myb domain and able to bind telomeric DNA, at least in vitro, as TRFL1 proteins family, but their single or multiple abrogation do not alter telomere length or generate phenotypes associated with telomere dysfunction, so they are not ...
InArabidopsisthere are five members of the TRB family (TRB1-5), but only TRB1, 2, and 3 are involved in telomere metabolism [102]. These proteins possess a myb-like domain at the N-terminus through which they can bind telomeric double stranded DNA (Fig.2C). Thanks to a histone-like...
Investigating Telomeres and What They Mean for Aging-Related Diseases (Posted 2012-12-11 05:14:08) ; Carol Greider Won the 2009 Nobel Prize for Her Work on Telomeres, the Caps on the Ends of Chromosomes. Now Scientists Are Trying to Figure out What That May Tell Us about Aging and ...
: So just what is a Telomere or its plural Telomeres. To grasp the power of Product B IsaGenesis, it's important to understand telomeres, the very element Product B IsaGenesis aims to support. Telomeres are the protective caps at the ends of our cells chromosomes. They protect our DNA ...
In mammals, telomeres are composed of TTAGGG repeats, which are bound by a protein complex termed shelterin. Cell divisions lead to the progressive erosion of telomeric repeats. When telomeres become too short to recruit the shelterin complex, they become dysfunctional, leading to telomere ...
these cells are unable to fully eliminate malignancies and provide durable and persistent protection against cancer. So, what if you could lengthen these DNA-protein structures found at the end of chromosomes during the ex-vivo manufacturing of CAR T cells, i.e., before they are put back into...
