Abstract

See full text

This application relates to recombinant human interferon-like proteins. In one embodiment a recombinant protein created by gene shuffling technology is described having enhanced anti-viral and anti-proliferative activities in comparison to naturally occurring human inteferon like alpha 2b(HuIFN-α2b). The invention encompasses a polynucleotide encoding the protein and recombinant vectors and host cells comprising the polynucleotide. Preferably the polynucleotide is selected from the group of polynucleotides each having a sequence at least 93% identical to SEQ ID: No. 1 and the protein is selected from the group of proteins each having an amino acid sequence at least 85% identical to SEQ ID No: 2. The proteins and compositions comprising the proteins can be used for treatment of conditions responsive to interferon therapy, such as viral diseases and cancer.
