CC   -!- FUNCTION: Produced by macrophages, IFN-alpha have antiviral activities.
CC       Interferon stimulates the production of two enzymes: a protein kinase
CC       and an oligoadenylate synthetase.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the alpha/beta interferon family. {ECO:0000305}.
