What's a GeneRIF?

DDX46 inhibits antiviral innate responses by entrapping selected antiviral transcripts in the nucleus by erasing their m(6)A modification, a modification normally required for export from the nucleus and translation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
