ABSTRACT:
The invention provides antitumor therapeutic methods employing bovine or ovine interferon-tau (IFN-.tau.) proteins and polypeptides. The IFN-.tau. proteins exhibit the antiviral and antiproliferative properties characteristic of type I interferons. An advantage of the invention is that IFN-.tau. has essentially no cytotoxic effects on treated cells as does, for example, IFN-.alpha..
