Telomeric Repeat Binding Factor 1

Telomeric Repeat Binding Factor 1 (TRF1) is a protein that plays a crucial role in maintaining the stability of chromosomes, the structures that carry our genetic information. It specifically binds to the ends of chromosomes called telomeres, which protect the genetic material during cell division. By regulating telomere length and structure, TRF1 helps prevent chromosomes from deteriorating or fusing together, which could lead to cell malfunction or aging. Proper function of TRF1 is essential for healthy cell growth and is also linked to aging and cancer development when its regulation is disrupted.
