Abstrakt: RNA modifications are integral to the regulation of RNA metabolism. One abundant mRNA modification is N 6 -methyladenosine (m 6 A), which affects various aspects of RNA metabolism, including splicing, translation and degradation. Current knowledge about the proteins recruited to m 6 A to carry out these molecular processes is still limited. Here we describe comprehensive and systematic mass-spectrometry-based screening of m 6 A interactors in various cell types and sequence contexts. Among the main findings, we identified G3BP1 as a protein that is repelled by m 6 A and positively regulates mRNA stability in an m 6 A-regulated manner. Furthermore, we identified FMR1 as a sequence-context-dependent m 6 A reader, thus revealing a connection between an mRNA modification and an autism spectrum disorder. Collectively, our data represent a rich resource and shed further light on the complex interplay among m 6 A, m 6 A interactors and mRNA homeostasis.
