Function

[YTDC1_HUMAN] RNA-binding protein that regulates alternative splice site selection.^[1]

Publication Abstract from PubMed

N6-methyladenosine (m(6)A) is the most prevalent chemical modification in human mRNAs. Its recognition by reader proteins enables many cellular functions, including splicing and translation of mRNAs. However, the binding mechanisms of m(6)A-containing RNAs to their readers are still elusive due to the unclear roles of m(6)A-flanking ribonucleotides. Here, we use a model system, YTHDC1 with its RNA motif 5'-G-2G-1(m(6)A)C+1U+2-3', to investigate the binding mechanisms by atomistic simulations, X-ray crystallography, and isothermal titration calorimetry. The experimental data and simulation results show that m(6)A is captured by an aromatic cage of YTHDC1 and the 3' terminus nucleotides are stabilized by cation-pi-pi interactions, while the 5' terminus remains flexible. Moreover, simulations of unbound RNA motifs reveal that the methyl group of m(6)A and the 5' terminus shift the conformational preferences of the oligoribonucleotides to the bound-like conformation, thereby facilitating the association process. The binding mechanisms may help in the discovery of chemical probes against m(6)A reader proteins.
