YTHDF3 (human), recombinant protein

Protein function: Specifically recognizes and binds N6-methyladenosine (m6A)- containing RNAs and promotes RNA translation efficiency (PubMed:28106072, PubMed:28106076, PubMed:28281539). 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 (PubMed:22575960, PubMed:24284625, PubMed:28106072, PubMed:28106076, PubMed:28281539). Shares m6A-containing mRNAs targets with YTHDF1 and YTHDF2, and regulates different processes depending on the context (PubMed:28106072, PubMed:28106076). Facilitates the translation of targeted mRNAs in cooperation with YTHDF1 by binding to m6A-containing mRNAs and interacting with 40S and 60S ribosome subunits (PubMed:28106072, PubMed:28106076). Acts as a negative regulator of type I interferon response by down-regulating interferon-stimulated genes (ISGs) expression: acts by binding to FOXO3 mRNAs and promoting their translation. Binds to FOXO3 mRNAs independently of METTL3- mediated m6A modification. Can also act as a regulator of mRNA stability in cooperation with YTHDF2 by binding to m6A- containing mRNA and promoting their degradation (PubMed:28106072). Recognizes and binds m6A-containing circular RNAs (circRNAs) and promotes their translation (PubMed:28281539). circRNAs are generated through back-splicing of pre-mRNAs, a non-canonical splicing process promoted by dsRNA structures across circularizing exons (PubMed:28281539).
