抗异染色质蛋白1α抗体(克隆号2HP-1H5)是小鼠单克隆抗体,用于检测异染色质蛋白1α(又名HP1a、抗原p25、色素框同源蛋白5)。已通过ELISA、ICC、IHC方法验证。

Biochem/physiol Actions

在氨基酸67和119之间与异染色质蛋白-1α(HP1α)反应。

General description

染色质组装因子-1(CAF-1)是一种多亚基蛋白质复合物,包含三个称为p150,p60和p48的多肽亚基。CAF-1是一种核小体组装因子,在DNA复制过程中将新合成的和乙酰化的组蛋白H3/H4沉积到新生的染色质中。

异染色质的特征是密集卷曲的染色质,通常在S期后期复制,基因密度低,并且包含大块重复DNA,而DNA修饰试剂相对无法获得。在S期晚期,p150与异染色质相关蛋白1(HP1α、HP1β和HP1γ)直接缔合。随着细胞准备有丝分裂,CAF-1 p150和一些HP1逐渐从异染色质上解离,这与组蛋白H3的磷酸化相吻合。由于组蛋白H3被去磷酸化,HP1蛋白在有丝分裂结束时与染色质重新结合。

Immunogen

重组小鼠HP1a蛋白。
