我们已经开发了一种称为PUB-NChIP(利用天然ChIP的生物素化的邻近)的方法来纯化和研究与感兴趣的核蛋白邻近的染色质的蛋白质组成。它基于(1)与细菌生物素连接酶BirA融合的目标蛋白,以及(2)与生物素受体肽(BAP)融合的组蛋白的共表达,BAP在目标蛋白附近通过BirA融合特异性生物素化。使用的RAD 18蛋白作为一个模型,我们表明,RAD 18近端染色质是丰富的一些H4乙酰化的物种。此外,含有替换组蛋白H2 AZ的RAD 18近端染色质具有不同的H4乙酰化模式。最后,生物素脉冲追踪实验表明,H4乙酰化模式开始类似于总H4的乙酰化模式后,染色质的接近RAD 18已经失去。
We have developed an approach termed PUB-NChIP (proximity utilizing biotinylation with native ChIP) to purify and study the protein composition of chromatin in proximity to a nuclear protein of interest. It is based on coexpression of (1) a protein of interest, fused with the bacterial biotin ligase BirA, together with (2) a histone fused to a biotin acceptor peptide (BAP), which is specifically biotinylated by BirA-fusion in the proximity of the protein of interest. Using the RAD18 protein as a model, we demonstrate that the RAD18-proximal chromatin is enriched in some H4 acetylated species. Moreover, the RAD18-proximal chromatin containing a replacement histone H2AZ has a different pattern of H4 acetylation. Finally, biotin pulse-chase experiments show that the H4 acetylation pattern starts to resemble the acetylation pattern of total H4 after the proximity of chromatin to RAD18 has been lost.
