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。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.
