ENCODES a protein that exhibits 2'-5'-oligoadenylate synthetase activity (ortholog); double-stranded RNA binding (ortholog); INVOLVED IN negative regulation of viral genome replication (ortholog); response to virus (ortholog); PARTICIPATES IN hepatitis C pathway; influenza A pathway; measles pathway
This gene is a member of the 2'-5' oligoA synthetase family, which are clustered on chromosome 5. The encoded protein functions in the interferon-regulated OAS/RNase L system, which mediates RNA decay as part of the innate antiviral immunity pathway. The protein binds double-stranded RNA and oligome
rizes ATP, which activate the single-stranded RNA cleavage enzyme RNase L. This protein mediates resistance to flaviviruses such as West Nile virus. The majority of wild mouse strains produce a functional protein and are resistant to flavivirus infection, whereas some inbred mouse strains including the strain of the reference genome, C57BL/6J, contain a premature stop codon that inactivates this gene product.

This gene encodes a member of the oligoadenylate synthetase family of proteins. This gene and several other family members are present in a gene cluster on chromosome 5. These proteins are believed to function in antiviral immunity through binding to viral dsRNA and subsequent synthesis of 2'-5'-oli
goadenylates. The expression of this gene has been shown to be induced by interferon. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Nov 2014]
