Oas1a Gene Summary [Rat]

Enables 2'-5'-oligoadenylate synthetase activity. Predicted to be involved in several processes, including cellular response to cytokine stimulus; regulation of cytokine production; and regulation of innate immune response. Located in nucleus. Human ortholog(s) of this gene implicated in immunodeficiency 100. Orthologous to human OAS1 (2'-5'-oligoadenylate synthetase 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Oas1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • Second Messenger Oligonucleotide or Dinucleotide Synthetase domain
  • 2'-5'-oligoadenylate synthetase 1, domain 2, C-terminus
  • Nucleotidyltransferase (NT) domain of DNA polymerase beta and similar proteins
  • double-stranded RNA binding
  • enzyme
  • protein binding
  • 2'-5'-oligoadenylate synthetase
