ABSTRACT:
A IFN-.beta. mutein in which phe (F), tyr (Y), trp (W) or his (H) is substituted for val (V) at position 101, when numbered in accordance with wild type IFN-.beta., DNA sequences encoding these IFN-.beta. muteins, recombinant DNA molecules containing those DNA sequences operatively linked to expression control sequences and capable of inducing expression of an IFN-.beta. mutein, hosts transformed with those recombinant DNA molecules, pharmaceutical compositions containing IFN-.beta. muteins and methods for treating viral infections, cancer or tumors, undesired cell proliferation, or for immunomodulation.
