  • Patent number: 9765321
    Abstract: Novel promoters which are derived from P. pastoris pastoris which are inducible or repressible under specific growth conditions are provided. These promoters are useful for regulating the expression of a desired structural gene, e.g., a mammalian polypeptide. Particularly preferred is the use of these novel promoters to regulate gene expression in polyploidal yeast such as diploidal P. pastoris produced by mating or spheroplast fusion.

  • Patent number: 8709756
    Abstract: Methods are provided for the synthesis and secretion of recombinant hetero-multimeric proteins in mating competent yeast. A first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

  • Patent number: 7927863
    Abstract: Methods are provided for the synthesis and secretion of recombinant proteins preferably large mammalian proteins or hetero-multimeric proteins at high levels and for prolonged time in polyploid, preferably diploid yeast. These methods use various mating competent yeast, including Pichia. In a preferred embodiment, a first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.
