  • Patent number: 9340617
    Abstract: The present invention relates generally to the field of generating fusion proteins to be used in cancer therapy, and more specifically, to nucleotide sequences encoding the fusion proteins, wherein the chimeric fusion proteins comprises at least one targeting moiety and at least one immunomodulatory moiety that counteracts the immune tolerance of cancer cells.
    Type: Grant
    Filed: August 13, 2014
    Date of Patent: May 17, 2016
    Assignee: BIOCON LIMITED
    Inventors: Nagaraj Govindappa, Kedarnath Sastry, Maria Melina Soares
  • Publication number: 20160009807
    Abstract: The present invention relates generally to the field of generating recombinant chimeric fusion proteins to be used in the cancer therapy, and more specifically, to fusion molecules of Anti-EGFR1-TGF?RII, Anti-EGFR1-PD1 and Anti-CTLA4-PD1 and methods of generating same, wherein the methods reduce production costs and increase homogeneity of the recombinant chimeric fusion proteins.

  • Publication number: 20150118710
    Abstract: The disclosure relates to a process of obtaining a fully folded two chain insulin glargine that require no further processing to make it functionally active. The present disclosure discloses a surprising effect of over expression of Kex2p intracellularly under the control of inducible FLD1 promoter in the host Pichia pastoris to produce two chain functional glargine secreted directly in the medium. The schematic diagram of how the two chains are made inside the host Pichia pastoris and secretes into the medium.

  • Patent number: 8975041
    Abstract: The present invention relates to novel Prolipase-Bovine trypsinogen (PLBTR) fusion proteins, the genes encoding them, and the production and uses thereof. More specifically, the present invention relates to methods of producing in optimal quantities PLBTR fusion proteins which comprise a heterologous polypeptide which is normally susceptible to autocatalytic activity. More particularly, the present invention relates to fusion proteins which comprise an heterologous polypeptide, such as a serine protease, fused to a lipase signal sequence, which can be expressed by recombinant host cells in desired amounts. The present invention further relates to polynucleotides encoding such fusion proteins, to expression vectors for expression of such fusion proteins, to host cells transformed with such polynucleotides/vectors, and to methods of generating such fusion proteins.

  • Patent number: 8778659
    Abstract: The disclosure relates to method of reducing O-glycosylation levels of the insulin or insulin analog precursor molecule produced by Pichia sp. The present disclosure provides genetically engineered knock-out strains of methylotrophic yeast including Pichia and especially Pichia pastoris by disruption of Protein mannosyl transferase (PMT) genes and rendering them capable of producing heterologous proteins with reduced glycosylation. Vectors, which comprise coding sequences for PMT1, PMT2, PMT4, PMT5, and PMT6 genes, for transforming methylotrophic yeasts are contemplated by the present disclosure. PMT inactivated strains of this disclosure have been deposited at MTCC, Chandigarh. The strains are PMT1/GS115 (MTCC 5515), PMT4/GS115 (MTCC 5516), PMT5/GS115 (MTCC 5517) and PMT6/GS115 (MTCC 5518).
