Summary: Enables 2'-5'-oligoadenylate synthetase activity and double-stranded RNA binding activity. Involved in purine nucleotide biosynthetic process. Acts upstream of or within negative regulation of viral process. Predicted to be located in mitochondrion; nucleus; and ribosome. Predicted to be active in cytosol; membrane; and nucleoplasm. Predicted to colocalize with cytoplasm. Is expressed in appendicular skeleton; axial skeleton; lower jaw; and testis. Orthologous to human OAS1 (2'-5'-oligoadenylate synthetase 1).

What's a GeneRIF?

Thus, activation of RNase L does not require mouse hepatitis virus virus-induced interferon but rather correlates with adequate levels of basal Oas gene expression, maintained by basal interferon signaling.
Title: Activation of RNase L by Murine Coronavirus in Myeloid Cells Is Dependent on Basal Oas Gene Expression and Independent of Virus-Induced Interferon.
Mouse hepatitis virus Ns2 cleaves 2',5'-oligoadenylate, the product of 2',5'-oligoadenylate synthetase, to prevent activation of the cellular endoribonuclease RNase L and consequently block viral RNA degradation.
Title: Antagonism of the interferon-induced OAS-RNase L pathway by murine coronavirus ns2 protein is required for virus replication and liver pathology.
Activation of Oas1a gene expression by type I IFN requires both STAT1 and STAT2
Title: Activation of Oas1a gene expression by type I IFN requires both STAT1 and STAT2 while only STAT2 is required for Oas1b activation.
In the absence of a functional OAS1a pathway, herpes simplex virus type 1 antigen expression is more widespread, and the ability of IFN-beta transgene treatment to reduce infectious HSV-1 in eyes and trigeminal ganglia is lost.
Title: Critical role for the oligoadenylate synthetase/RNase L pathway in response to IFN-beta during acute ocular herpes simplex virus type 1 infection.

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.
