补充资料:沉默子
沉默子(silencer)是参与基因表达负调控的一种元件,是在研究t淋巴细胞的t抗原受体(tcr)基因表达调控时发现的。tcr有α/β、γ/δ两种,编码α链和δ链是同一基因座的两个等位基因,α链恒定区ca基因3’端下游的。增强子在各种t细胞中都有可能表达。因此,在t细胞分化时,需要通过各种正负调控机制进行精确的选择,方能正确地表达。已知有3个负调控元件,一个紧接在ca基因的3’下游,另一个则在co增强子的上游。对α基因专一的沉默子的作用是阻止ja基因在γ/δ型 t 细胞中参与重排,使 ja 基因只参与α/β型t细胞中的重排。这说明α沉默子对在α和δ两个等位基因中选择。等位基因的转录和重排时起作用,而使δ等位基因沉默。这些负调控元件不受距离和取向的限制。
