  • Patent number: 9862956
    Abstract: The invention is generally directed to modified filamentous fungal host cells comprising one or more nucleic acids encoding one or more polypeptides under the control of one or more promoters that are functional in said cells. Methods of using the modified cells to express one or more polypeptides are also disclosed, including methods of screening cells transformed with one or more expression vectors comprising nucleic acids derived from synthetic or genomic nucleic acids including, cDNAs. Methods of purifying one or more polypeptides or complexes comprising one or more polypeptides expressed in the modified cells, intended for use as substrates in structure/function studies, as therapeutic agents, as diagnostic reagents, or as human or animal vaccines, are also disclosed.
    Type: Grant

  • Patent number: 8680252
    Abstract: The invention provides a method for the expression and subsequent screening of DNA libraries, particularly synthetic, genomic, and cDNA libraries, in filamentous fungal hosts. In particular, the invention provides vectors, host strains, and a method for the expression and screening of complex DNA libraries, including, but not limited to, combinatory (combinatorial) libraries expressing one, two or more variable constituents and/or prepared from two or more sublibraries (e.g., for the expression and screening of immunoglobulin (including fragments and derivatives of whole immunoglobulin proteins) and other receptor or complex DNA libraries or libraries of libraries). The invention is useful for the expression and screening for a large variety of proteins and protein complexes, including human proteins. The present invention also relates to novel fungal protease sequences.

  • Patent number: 7794962
    Abstract: The invention provides a method for the expression of exogenous DNA libraries in filamentous fungi. The fungi are capable of processing intron-containing eukaryotic genes, and also can carry out post-translational processing steps such as glyclosylation and protein folding. The invention provides for the use of fungi with altered morphology, which permits high-throughput screening and directed molecular evolution of expressed proteins. The same transformed fungi may be used to produce larger quantities of protein for isolation, characterization, and application testing, and may be suitable for commercial production of the protein as well.
