    摘要: 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 interferon 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.

    摘要: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo in comparison to naturally occurring or recombinant native human erythropoietin. In one embodiment of the invention, the protein has a half-life in vivo at least three fold higher than native human erythropoietin. The fusion protein also exhibits enhanced erythropoietic bioactivity in comparison to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human immunoglobulin IgG1. The Fc fragment in the fusion protein includes the hinge region, CH2 and CH3 domains of human immunoglobulin IgG1. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen the risk of an immunogenic response when administered in vivo. In one embodiment the hinge region is a human Fc fragment variant having a non-cysteine residue at amino acid 6. The invention also relates to nucleic acid and amino acid sequences encoding the fusion protein and transfected cell lines and methods for producing the fusion protein. The invention further includes pharmaceutical compositions comprising the fusion protein and methods of using the fusion protein and/or the pharmaceutical compositions, for example to stimulate erythropoiesis in subjects in need of therapy.

    摘要: A fusion protein having a non-immunoglobulin polypeptide having a cysteine residue proximal to the C terminal thereof, and an immunoglobulin component with a mutated hinge region is provided. The mutation comprises a point mutated site corresponding in position to the position in a native hinge region of the cysteine residue located nearest the cysteine residue of the non-Ig component. The distance from the cysteine residue of the non-immunoglobulin polypeptide and any remaining cysteine residues of the mutated hinge region is sufficient to prevent the formation of a disulphide bond therebetween.
