MBD4 (methyl-CpG binding domain protein 4)

MBD4 is a specialized protein that plays a crucial role in DNA repair, particularly at sites where DNA has undergone chemical changes called methylation. It recognizes and binds to specific methylated DNA regions, helping correct mutations that could otherwise lead to errors in genetic information. By maintaining DNA integrity, MBD4 helps prevent diseases like cancer. Essentially, it acts as a quality control agent, ensuring the genetic code remains accurate and stable, which is vital for healthy cell function and overall organism health.
