== Function ==
[https://www.uniprot.org/uniprot/YTHD2_HUMAN YTHD2_HUMAN] Specifically recognizes and binds N6-methyladenosine (m6A)-containing RNAs. M6A is a modification present at internal sites of mRNAs and some non-coding RNAs and plays a role in the efficiency of mRNA splicing, processing and stability. Acts as a regulator of mRNA stability: binding to m6A-containing mRNAs results in the localization of to mRNA decay sites, such as processing bodies (P-bodies), leading to mRNA degradation.<ref>PMID:22575960</ref> <ref>PMID:24284625</ref>

== Publication Abstract from PubMed ==
We report 17 small-molecule ligands that compete with N6-methyladenosine (m(6)A) for binding to the m(6)A-reader domain of YTHDF2 (YT521-B homology domain family 2). We determined their binding mode at high resolution by X-ray crystallography and quantified their affinity by a fluorescence-based binding assay. 6-Cyclopropyluracil and a pyrazolopyrimidine derivative have favorable ligand efficiencies of 0.47 and 0.38 kcal mol(-1) per non-hydrogen atom, respectively. They represent useful starting points for hit optimization.
