    摘要: The present invention relates to novel host cells and to methods of producing proteins. More specifically the invention relates to a host cell useful for the expression of heterologous proteins, which host cell has been genetically modified in order to express significantly reduced levels of a metalloprotease. Moreover the invention relates to a method of producing a heterologous protein, which method comprises cultivating the host cell in a suitable growth medium, followed by recovery of the desired protein.

    摘要: The present invention relates to a filamentous fungal cell in which an endogenous alkaline protease activity, an endogenous neutral metalloprotease activity and an endogenous serine protease activity of the subtilisin type have been completely or partially inactivated. Particularly the endogenous alkaline protease activity, the endogenous neutral metalloprotease activity and the endogenous serine protease activity of the subtilisin type are encoded by the alp, npI and pepC genes respectively. The filamentous fungal cell is particularly suitable for production of heterologous proteins such as antibodies.
