BMI-1 (B lymphoma Mo-MLV insertion region 1 homolog) atau "Polycomb complex protein BMI-1" dikenal juga sebagai "polycomb group RING finger protein 4 (PCGF4)" atau "RING finger protein 51 (RNF51)" adalah protein pada manusia yang disandi oleh gen BMI1 (B cell-specific Moloney murine leukemia virus integration site 1).^[3]^[4] BMI1 adalah suatu onkogen polycomb ring finger.

Fungsi

BMI-1 telah dilaporkan sebagai onkogen dengan mengatur p16 dan p19, yang merupakan gen penghambat sel siklus. Bmi1 knockout pada tikus menyebabkan cacat dalam hematopoiesis, pola kerangka, fungsi neurologis, dan perkembangan otak kecil. Baru-baru ini telah dilaporkan BMI-1 secara cepat direkrut ke situs kerusakan DNA dan mampu bertahan selama lebih dari 8 jam. Hilangnya BMI1 menyebabkan radiasi sensitif dan putusnya untai ganda DNA (DNA double-strand breaks) oleh rekombinasi homolog 10.
