  • Patent number: 8592192
    Abstract: A strategy to improve protein stability by domain insertion. TEM 1 beta-lactamase (BLA) and exo-inulinase, as model target enzymes, are inserted into a hyperthermophilic maltose binding protein from Pyrococcus furiosus (PfMBP). Unlike conventional protein stabilization methods that employ mutations and recombinations, the inventive approach does not require any modification on a target protein except for its connection with a hyperthermophilic protein scaffold. For that reason, target protein substrate specificity was largely maintained, which is often modified through conventional protein stabilization methods. The insertion was achieved through gene fusion by recombinant DNA techniques.

  • Patent number: 6696415
    Abstract: Tubedown-1 (tbdn-1), a protein associated with acetyltransferase activity has been characterized and its cDNA isolated. Tbdn-1 regulates endothelial differentiation through protein acetylation, DNA-binding or by interacting with and/or acetylating other protein targets important for endothelial differentiation. In normal adult eyes, tbdn-1 is expressed highly in the corneal endothelium proper and in the vascular endothelium of the limbus and retina. Tbdn-1 is absent or downregulated in the vascular endothelia of diseased and injured eyes, including eyes from patients with proliferative retinopathies involving neovascularization. Inhibition of tbdn-1 expression in endothelial cells in vitro indicates tbdn-1 acts as an inhibitor of angiogenesis. Thus, high levels of tbdn-1 expression present in normal ocular endothelial cells is associated with suppression of abnormal neovascularization in the eye demonstrating the therapeutic usefulness of tbdn-1 as a regulator of retinal angiogenesis.

  • Publication number: 20040018573
    Abstract: Described herein are methods for the production of monoclonal antibodies in filamentous fungi host cells. The monoclonal antibodies are expressed as full-length fusion proteins that retain functional antigen binding and antibody-dependent cellular cytotoxicity capabilities. Improvements in the cleavage of the glucoamylase-light chain fusion protein to yield a mature antibody are also provided. The antibodies produced in filamentous fungi show equivalent pharmacokinetic disposition to antibodies produced in mammalian cells.
