N6-甲基腺苷 (m6A) 是真核生物中普遍存在的 mRNA“表观遗传调控”研究中广泛研究的一种 RNA 修饰。 m6A水平的异常变化与RNA代谢的调节、热休克应激、肿瘤的发生、发展密切相关。 m6A 修饰由 m6A writer 复合物催化,该复合物包含 RNA 甲基转移酶样 3 (METTL3)、甲基转移酶样 14 (METTL14)、Wilms 肿瘤 1 相关蛋白 (WTAP) 和其他具有甲基转移酶 (MTase) 功能的蛋白,例如 RNA 结合基序蛋白 15 (RBM15), KIAA1429和锌指CCCH型含有13(ZC3H13)。虽然 METTL3 是主要催化亚基,但 WTAP 是调节亚基,其功能是将 m6A 甲基转移酶复合物招募到靶 mRNA 上。具体来说,核散斑中 METTL3 和 METTL14 的积累需要 WTAP。本文简要介绍了m6A修饰的分子机制。然后,我们重点介绍m6A甲基转移酶复合物的组成部分WTAP,并介绍其结构、定位和生理功能。最后,我们描述了它在癌症中的作用和机制。
N6-methyladenosine (m6A) is a widely investigated RNA modification in studies on the “epigenetic regulation” of mRNAs that is ubiquitously present in eukaryotes. Abnormal changes in m6A levels are closely related to the regulation of RNA metabolism, heat shock stress, tumor occurrence, and development. m6A modifications are catalyzed by the m6A writer complex, which contains RNA methyltransferase-like 3 (METTL3), methyltransferase-like 14 (METTL14), Wilms tumor 1-associated protein (WTAP), and other proteins with methyltransferase (MTase) capability, such as RNA-binding motif protein 15 (RBM15), KIAA1429 and zinc finger CCCH-type containing 13 (ZC3H13). Although METTL3 is the main catalytic subunit, WTAP is a regulatory subunit whose function is to recruit the m6A methyltransferase complex to the target mRNA. Specifically, WTAP is required for the accumulation of METTL3 and METTL14 in nuclear speckles. In this paper, we briefly introduce the molecular mechanism of m6A modification. Then, we focus on WTAP, a component of the m6A methyltransferase complex, and introduce its structure, localization, and physiological functions. Finally, we describe its roles and mechanisms in cancer.
