摘要:

组蛋白去甲基化酶KDM7家族包括KDM7A、KDM7B、KDM7C三种蛋白,主要通过去除与转录沉默相关的特定组蛋白赖氨酸甲基化修饰,进而对基因转录发挥调控作用。目前,对KDM7家族的研究主要集中于其在神经分化、肿瘤发生发展等过程中的作用,而对其在脑神经疾病中的作用却知之甚少。本文从该蛋白家族表观遗传调控机制、结构生物学及其在脑神经疾病中的作用等方面进行了综述,以期为研究其在脑神经疾病中的功能机制提供参考,为理解脑神经疾病分子病理机制以及探索基于该机制的有效治疗靶点带来新的启示。

Abstract:

The histone demethylases of KDM7 family, including KDM7A, KDM7B and KDM7C, regulate transcription through acting on specific histone lysines. Previous studies have shown that these family members are functionally important for the processes of neural differentiation and tumor development, and little is known about their roles in brain neurological diseases. In this review, we summarize the latest research progress of KDM7 family on their epigenetic regulation mechanisms, their protein structures and their functions in brain-related diseases, which will likely advance our understanding of the molecular mechanisms of neurological diseases.

Key words: histone lysine demethylases, KDM7, H3K9me2, H3K27me2
