    basic FUNCTION
  • mediating resistance to virus infection, control of cell growth, differentiation and apoptosis
  • plays a central role in the cellular innate antiviral response
  • is one of the major interferon-inducible proteins and a critical component of the host defense system against viral infection
  • potential role of OAS1 polymorphisms in respiratory infection
  • recognizes double-stranded RNA (dsRNA) using a previously uncharacterized protein/RNA interface that forms via a conformational change induced by binding of dsRNA
  • CELLULAR PROCESS cell life, differentiation
