TRF1 (Telomeric Repeat Binding Factor 1)

TRF1, or Telomeric Repeat Binding Factor 1, is a protein that plays a crucial role in protecting the ends of chromosomes, known as telomeres. Telomeres are protective caps that prevent the DNA from fraying or fusing with other chromosomes, which is important for maintaining genetic stability. TRF1 helps regulate the length of these telomeres and ensures they function properly. When telomeres become too short, it can lead to cell aging and contribute to diseases like cancer. Essentially, TRF1 is vital for preserving the integrity of our genetic material over time.
