Insect sequences for improving the efficiency of secretion of non-secreted proteins in eukaryotic cells

摘要

An expression cassette useful for the secretion of a heterologous protein from eukaryotic cells comprising a DNA sequence encoding a promoter functionally linked to a DNA sequence coding for the juvenile hormone esterase gene which is linked in frame to a heterologous gene is disclosed. Also disclosed is a method of secreting heterologous proteins in eukaryotic cells.
