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。
