The mRNA m6A modification has been characterized biochemically, molecularly, and phenotypically, including elucidation of its methyltransferase complexes (m6A writer), demethylases (m6A eraser), and direct interaction proteins (readers), while limited information on the DNA m6dA is available.
学术争鸣 | 从迷雾重重到柳暗花明?全面起底DNA 6mA修饰相关研 …
该研究发现哺乳动物中的6mA修饰主要集中在线粒体DNA上(平均每个mtDNA分子有4个6mA),而核基因组DNA的6mA量极低。同时,研究者鉴定了主要定位在线粒体中的METTL4,是6mA的甲基转移酶(这与南加州大学医学院的Douglas E. Feldman教授的结论一致,但他们当时认 …
RNA m6A甲基化修饰和特定基因m6A位点的检测方法|干货分享
N6-甲基腺苷 (N6-methyladenosine, m6A)是真核生物mRNA中最丰富的化学修饰,在基因表达调控中发挥着重要作用,包括转录调控和转录后调控。 m6A是一种可逆修饰,分别由 甲基转移酶 (writer)、 去甲基化酶 (eraser)和 m6A结合蛋白 (reader)进行添加、去除和识别。 m6A检测技术的发展是研究m6A功能的基础。 薄层色谱(TLC)、斑点印迹(dot-blots)以及液相色谱-串联质谱(LC-MS/MS)是广泛用于检测RNA m6A整体水平变化的方法。 然而这些方法无法分析m6A在 …
N6-Methyladenosine, DNA Repair, and Genome Stability - Frontiers
2021年4月8日 · DNA damage agents induce strand breaks to activate DNA damage response and ATM, which phosphorylates and activates METTL3. DNA damage response then leads to gene transcription and production of m 6 A by activated METTL3 on mRNA transcripts.
Emerging Roles for DNA 6mA and RNA m6A Methylation in …
2023年9月9日 · Epigenetic methylation has been shown to play an important role in transcriptional regulation and disease pathogenesis. Recent advancements in detection techniques have identified DNA N6-methyldeoxyadenosine (6mA) and RNA N6-methyladenosine (m6A) as methylation modifications at the sixth position of adenine in DNA and RNA, respectively.
