retinoblastoma protein

The retinoblastoma protein (Rb) is a crucial molecule in our cells that acts as a regulator of cell growth and division. It functions like a brake, preventing cells from dividing uncontrollably. When Rb is functioning normally, it helps keep cell growth in check, reducing the risk of cancers. If the Rb protein is damaged or not working properly, cells can grow uncontrollably, leading to tumor development, such as retinoblastoma—a type of eye cancer. Overall, Rb plays an essential role in maintaining healthy cell growth and preventing cancer formation.
