P16 gene is composed of two intervening sequences and three exons , and encodes p16 protein , which is the inhibiter of CDK4 and CDK6 . They can together prevent phosphorylation deactivation of pRB , and make the cell cycle blocked in G1 stage. P16 gene promoter region has a great of CpG islands , which can be methylated when some adverse factor appears , and so the genetic transcription of p16 can be inhibited , which leads to gene silencing, cell paraplasm, and tumor generate.

抑癌基因p16编码蛋白P16 ，是细胞周期蛋白CDK4和CDK6抑制剂，它阻止pRB磷酸化失活，使细胞周期阻滞于G1期。P16基因启动子区域富含CpG岛，当受到各种有害因素影响时，容易发生甲基化，从而抑制P16基因转录，导致基因沉默，细胞异常增生，导致肿瘤的发生[5]。
