Valencia-Sánchez et al. have demonstrated that two histone post-translational modifications (PTMs) – H4K16 acetylation (H4K16ac) and H2BK120 ubiquitination (H2Bub) – enhance the methylation of H3K79 (H3K79me) by Dot1. This breakthrough indicates crosstalk between H4Kac/H2Bub/H3K79me and may improve our understanding of the role that Dot1/Dot1L plays in developmental processes and disease, including MLL1/KMT2A(MLL-r) leukemia.

组蛋白 PTM 串扰刺激 Dot1 甲基转移酶活性

巴伦西亚-桑切斯等人。已经证明，两种组蛋白翻译后修饰 (PTM) – H4K16 乙酰化 (H4K16ac) 和 H2BK120 泛素化 (H2Bub) – 增强了 Dot1 对 H3K79 (H3K79me) 的甲基化。这一突破表明 H4Kac/H2Bub/H3K79me 之间存在串扰，并可能提高我们对 Dot1/Dot1L 在发育过程和疾病（包括 MLL1/ KMT2A ( MLL-r ) 白血病）中所起作用的理解。
