Murine Leukemia Viral (bmi 1) Oncogene Homolog, Oncogene BMI 1, PCGF4, Polycomb Complex Protein BMI 1, RING Finger Protein 51

The Bmi1 oncogene has been shown to induce telomerase activity and immortalize human mammary epithelial cells. Bmi1 extends the replicative life span of human fibroblasts by suppressing the p16-dependent senescence pathway. Bmi1 is also important in maintaining stem cells' ability to self renew. It has also been termed an oncogene with aberrant expression in various carcinomas. It has been shown to be a negative regulator of p19Arf, Ink4a (p14Arf) and tp53 known tumor repressors. Ablation of Bmi1 is required for short term survival of cancer cells.

Positive Control: Human and mouse skeletal muscle
Applications
Suitable for use in Western Blot, Immunocytochemistry and Immunofluorescence. Other applications not tested.
Recommended Dilution
Western Blot: A band is seen at ~37kD. Some less intense non-specific bands are also present. Optimal dilutions to be determined by the researcher.
