Function

YTHD3_HUMAN Specifically recognizes and binds N6-methyladenosine (m6A)-containing RNAs, and regulates their stability (PubMed:28106072, PubMed:28106076, PubMed:28281539, PubMed:32492408). M6A is a modification present at internal sites of mRNAs and some non-coding RNAs and plays a role in mRNA stability and processing (PubMed:22575960, PubMed:24284625, PubMed:28106072, PubMed:28281539, PubMed:32492408).

Publication Abstract from PubMed

Three YTH-domain family proteins (YTHDF1, YTHDF2, and YTHDF3) recognize the N(6)-methyladenosine (m(6)A) modification of mRNA in cells. However, the redundancy of their cellular functions has been disputed. We investigate their interactions with m(6)A-containing RNA using X-ray crystallography and molecular dynamics (MD). The new X-ray structures and MD simulations show that the three proteins share identical interactions with the m(6)A-containing RNA and have similar intrinsic plasticity, thus evidencing the redundant roles of the three proteins in cellular functions.
