Bmi1

BMI1 is a protein found in our cells that plays a key role in regulating how cells grow and divide. It is part of a group called polycomb group proteins, which help turn off certain genes to maintain cell identity and function. BMI1 is especially important for stem cells, helping them stay flexible and healthy, and it also contributes to tissue renewal. However, in some cases like cancer, BMI1 can become overactive, leading to uncontrolled cell growth. Overall, BMI1 is essential for normal cell maintenance but must be carefully regulated to prevent disease.
