Polycomb Repressive Complex (PRC)

The Polycomb Repressive Complex (PRC) is a group of proteins that play a crucial role in regulating gene activity in cells. Think of it as a molecular "brake" that can switch off certain genes, preventing them from being expressed. This is important for maintaining the proper function of cells, especially during development and differentiation. By controlling when and where genes are active, PRC helps ensure that cells develop into their correct types and perform their specific roles in the body. Dysfunction in PRC can lead to a variety of diseases, including cancer.
