CTCF (CCCTC-binding factor)

CTCF (CCCTC-binding factor) is a protein that plays a key role in organizing the structure of our DNA inside the nucleus. It binds to specific DNA sequences and acts as an insulator, helping to regulate gene activity by controlling how different parts of the DNA interact. This organization ensures that genes are turned on or off at the right times, which is essential for proper development and function. In essence, CTCF acts as a molecular organizer, maintaining the proper architecture of genetic information to support healthy cellular processes.
