Crystal structure of the YTHDC1 YTH domain in complex with m6A-containing RNA revealed the specific mode of m6A binding; YTHDC1 preferentially recognizes GG(m6A)C sequences through an aromatic cage, with a distinctly selective binding pocket for the nucleotide preceding m6A that is absent in other YTH family members. |

Structural comparison of YTH domain proteins revealed that only YTHDC1 harbors a distinctly selective binding pocket for the nucleotide preceding the m6A modification; all YTH domains use a conserved aromatic cage to recognize m6A, but YTHDC1's selectivity for 5'-GGm6AC is unique. |
