几种急性淋巴细胞白血病和髓性白血病与人类混合谱系白血病蛋白-1(MLL 1)基因的改变相关。MLL 1是进化上保守的组蛋白H3赖氨酸4(H3 K4)甲基转移酶的SET 1家族的成员,该家族是后生动物中不同发育调控基因组调控所必需的。尽管SET 1家族酶的重要生物学作用及其与人类白血病的关系,但人们对这些酶如何工作的了解相对较少。在这里,我们回顾了最近的几个结构和生化研究,开始揭示了人类MLL 1酶调节H3 K4甲基化的分子机制。
Several acute lymphoblastic and myelogenous leukemias are correlated with alterations in the human Mixed Lineage Leukemia protein-1 (MLL1) gene. MLL1 is a member of the evolutionarily conserved SET1 family of histone H3 lysine 4 (H3K4) methyltransferases, which are required for the regulation of distinct groups of developmentally regulated genes in metazoans. Despite the important biological role of SET1 family enzymes and their involvement in human leukemia’s, relatively little is understood about how these enzymes work. Here we review several recent structural and biochemical studies that are beginning to shed light on the molecular mechanisms for the regulation of H3K4 methylation by the human MLL1 enzyme.
