Title: Targeting RNA oxidation by ISG20-mediated degradation is a potential therapeutic strategy for acute kidney injury.
ISG20 upregulated IFIT1 genes and inhibited translation of the alphavirus genome. Furthermore, IFIT1-sensitive alphavirus replication was increased in Isg20(-/-) mice compared to the replication of wild-type viruses but not in cells ectopically expressing ISG20.

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.

mRNA and Protein(s)

NM_001113527.1 → NP_001106999.1 interferon-stimulated gene 20 kDa protein isoform b

Status: VALIDATED

Description

Transcript Variant: This variant (2) differs in the 5' UTR and uses an alternate splice junction at the 5' end of the last exon compared to variant 4. The resulting isoform (b) has a shorter and distinct C-terminus compared to isoform a. Variants 1, 2, and 3 all encode the same isoform (b).
