BMI-1(B-cell-specific Moloney murine leukemia virus integration site 1), a Polycomb group repressor, is always present as a PcG complex combined with RING1, HPC2, Mph2, et al. BMI-1 prolongs cells'capacity to proliferate and represses their senescence by repressing the transcription of CDKN2A through acetylhydrolasing or deacetylhydrolasing the Polycomb response elements in chromosome.

BMI-1 (B-cell-specific Moloney murine leukemia virus integration site 1)属于PcG家族，它与该家族其他成员如RING1，HPC2，Mph2等结合形成蛋白复合体，作用于染色质PREs位点，通过对组蛋白进行乙酰化和去乙酰化修饰，从而稳定抑制CDKN2A转录，最终促进细胞的增殖并抑制细胞凋亡。
