About OAS2

Cytogenetic location: 12q24.13 Genomic coordinates (GRCh38): 12:112,978,519-113,011,723 (from NCBI)

This gene has 15 transcripts (splice variants), 110 orthologues and 3 paralogues. Broad expression in spleen (RPKM 18.2), lymph node (RPKM 14.1) and 22 other tissues.

Summary

This gene encodes a member of the 2-5A synthetase family, essential proteins involved in the innate immune response to viral Infection. The encoded protein is induced by interferons and uses adenosine triphosphate in 2'-specific nucleotidyl transfer reactions to synthesize 2',5'-oligoadenylates (2-5As). These molecules activate latent RNase L, which results in viral RNA degradation and the inhibition of viral replication. The three known members of this gene family are located in a cluster on chromosome 12. Alternatively spliced transcript variants encoding different isoforms have been described.
