SET domain bifurcated protein 1 (SETDB1) is a human histone-lysine methyltransferase which is amplified in human cancers and was shown to be crucial in the growth of non-small and small cell lung carcinoma. In addition to its catalytic domain, SETDB1 harbors a unique tandem tudor domain which recognizes histone sequences containing both methylated and acetylated lysines, and likely contributes to its
SET域分叉蛋白1(SETDB1)是一种人类组蛋白赖氨酸甲基转移酶,在人类癌症中被扩增,并且被证明对非小细胞肺癌和小细胞肺癌的生长至关重要。除其催化结构域外,SETDB1还具有独特的串联都铎结构域,该结构可识别同时含有甲基化和乙酰化赖氨酸的组蛋白序列,并可能有助于其在染色质上的定位。使用X射线晶体学和NMR光谱片段筛选方法,我们确定了第一个与SETDB1的串联Tudor域(TTD)的组蛋白肽结合槽结合的小分子片段。在本文中,我们描述了这些片段和类似物的结合模式以及关键化合物的生物物理特性。
