FUNGAL SIGNAL PEPTIDES

The present invention relates to nucleic acid constructs comprising a first polynucleotide encoding a signal peptide, e.g., from a fungal glycosidase, and a second polynucleotide encoding an alpha-lactalbumin (ALAB) polypeptide; expression vectors and host cells comprising said nucleic acid constructs; methods for producing ALAB polypeptides; and fusion proteins comprising an ALAB polypeptide and a signal peptide.
