Improved production of secreted proteins by filamentous fungi

摘要

The present invention relates to a method to improve the secretion of a protein of interest by a filamentous fungal cell comprising inducing a phenotype in the cell selected from the group consisting of a lowered ERAD, an elevated UPR that does not induce an elevated ERAD, wherein ERAD preferably is lowered. The invention further relates to the filamentous fungal cell comprising the phenotype described above. The invention also relates to polynucleotides and polypeptides whose expression can be modulated in the filamentous fungal cell to obtain the above-described phenotype.
