Abstract

The invention includes novel fusion nucleic acids encoding fusion polypeptides which when expressed in a filamentous fungus result in the expression of fusion polypeptides. The fusion nucleic acids comprise four nucleic acids which encode a fusion polypeptide comprising first, second, third and fourth amino acid sequences. The first nucleic acid encodes a signal polypeptide functional as a secretory sequence in a first filamentous fungus. The second nucleic acid encodes a secreted polypeptide or functional portion thereof which is normally secreted from the same filamentous fungus or a second filamentous fungus. The third nucleic acid encodes a cleavable linker while the fourth nucleic acid comprises at least two nucleic acids encoding desired polypeptides.
