Summary
The protein encoded by this gene contains a ribonuclease NYN domain and belongs to the N4BP1 family. The protein is a cofactor for the zinc finger antiviral protein (ZAP protein) which targets viral RNA for degradation and restricts SARS-CoV-2 infection. [provided by RefSeq, Sep 2021]

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.
