| 使用方法 | Recombinant YTHDF2 protein is suitable for use in protein-protein interaction and RNA binding assays. HTRF Assay: 3 µM m6A ssDNA oligos (5’-GTTGG/ m6A/CTT-3’) were incubated with YTHDF2 protein in binding buffer including 50 mM HEPES-NaOH pH 7.0, 0.1% BSA for 1 hour at RT. Anti-FLAG antibody was used to detect reaction products. Binding Assay: 45 pmol biotinylated m6A ssDNA oligos (DNA sequence: 5’-GTTGCCTGTTCGTGTTGG/m6A/ CTTGCCTGT-3’) were incubated with YTHDF2 protein in binding buffer including 25 mM Tris-HCl pH 7.4, 150 mM NaCl, 5% glycerol, 0.1% Triton X-100 for 3 hr at 4C. DNA-YTHDF2 compounds were incubated with streptavidin beads for 1 hr at 4C and pull-down products were run on a 10% SDS-PAGE gel, stained with Coomassie Blue. Biotinylated, unmethylated ssDNA oligos were used as negative control. YTHDF2 preferentially binds to ssDNA with m6A modification compared with unmodified ssDNA. |

| 背景 | N6-methylated adenine (m6A) is prevalently present in nearly all RNA types and can be found in all organisms from bacteria to humans. It preferentially appears around stop codons and within long internal exons in mammalian messager RNAs. m6A plays an important role in the efficiency of mRNA splicing, processing, translation efficiency, editing and mRNA stability. m6A is also found in other RNA molecules, such as primary miRNA (pri-miRNAs). YTHDF2 (YT521-B homology domain family 2, also known as CAHL, HGRG8, NY-REN-2) is a member of the YTH (YT521-B homology) superfamily containing YTH domain. Human YTH domain family proteins include three members, YTHDF1-3, which mainly localized in the cytoplasm. YTHDF proteins contain a highly conserved single-stranded RNA-binding domain which can specifically recognize and bind m6A-containing RNAs. An important role of YTHDF2 is in regulating mRNA stability. YTHDF2 recognizes many m6A-containing mRNAs that are not being actively translated and recruits them to cytoplasmic processing (P) bodies for degradation. YTHDF2 preserves 5′UTR methylation of stress- induced transcripts and promotes cap-independent mRNA translation by competitive binding and limiting the m6A ‘eraser’ FTO from demethylation. |
