TRF1

TRF1 (Telomeric Repeat-binding Factor 1) is a protein that binds specifically to the ends of chromosomes, called telomeres. Telomeres protect chromosomes from deterioration and prevent genetic information from being lost during cell division. TRF1 helps regulate and maintain telomere length, ensuring chromosome stability. Proper function of TRF1 is essential for healthy cell aging and preventing abnormal cell growth, such as cancer. It is a key part of the complex system that preserves genome integrity and supports normal cell life cycles.
