CTCF

CTCF (CCCTC-binding factor) is a protein that plays a crucial role in organizing our DNA within the cell nucleus. Think of it as a molecular organizer that helps create boundaries in the genome, ensuring that genes are properly regulated and not mistakenly turned on or off. By binding to specific DNA regions, CTCF helps form loops and domains, which are essential for controlling gene activity and maintaining genome stability. Its function is vital for normal development and preventing diseases like cancer by maintaining the proper structure and function of our genetic information.
