Abstract

N6-methyladenosine (m6A) is the most abundant modification in eukaryotic mRNAs, which plays an important role in regulating multiple biological processes. ATM is a major protein kinase that regulates the DNA damage response. Here, we identified that ATM is a m6A-modificated gene. METTL3 (a m6A “writer”) and FTO (a m6A “eraser”) oppositely regulated ATM expression and its downstream signaling. Mechanically, m6A “readers” YTHDFs and eIF3A suppressed ATM expression in the post-transcriptional levels. We also revealed the oncogenic potential of METTL3 and YTHDF1 related to ATM modulation. This is the first report that ATM, a master in the DNA damage response, is modified by m6A epigenetic modification, and METTL3 disrupts the ATM stability via m6A modification, thereby affecting the DNA-damage response.

Keywords: m6A modification, ATM, DNA damage response, METTL3, YTHDF1
