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