摘要 SET(patient SE translocation,SET)基因,又名模板活化因子-1(template activating factor,TAF-1),因首次鉴定于伴有该基因染色体异位的未分化型白血病患者SE而命名。SET蛋白具有多种生物功能,可以通过影响组蛋白乙酰化、转录调节、核小体装配等,参与基因表达调控、翻译后修饰、细胞凋亡等多个生物过程,是重要的细胞因子。一些消化和血液系统肿瘤、生殖与神经系统的疾病伴有SET表达或亚细胞定位异常,提示SET与这些疾病的发生发展相关。SET基因转录剪切产生TAF-Iα和SET/TAF-Iβ2个亚型,而SET/TAF-Iβ可能发挥着SET蛋白的主要生物学作用。
