RB1

RB1, short for retinoblastoma 1, is a gene that produces a protein acting as a tumor suppressor, meaning it helps regulate cell growth and prevent cancer. It plays a key role in controlling when cells divide and ensuring they don’t grow uncontrollably. When RB1 functions normally, it keeps cell growth in check. If this gene is mutated or not working properly, it can lead to uncontrolled cell division, increasing the risk of tumors, particularly in the eye (retinoblastoma) and other parts of the body. Essentially, RB1 acts as a crucial gatekeeper for healthy cell growth.
