Said oligomers are characterized in that the recombinant fusion proteins have at least one component A and at least one component B, whereby component A contains a protein or a protein segment with a biological function, in particular with a ligand function for antibodies, for soluble or membranous signal molecules, for receptors or an antibody, or an antibody segment, and component B contains a protein or a protein segment which dimerizes or oligomerizes the dimer, trimer, quatromer or pentamer of the recombinant fusion protein, without the action of third-party molecules. The invention also relates to the use of dimers or oligomers of this type for producing a medicament, to the fusion proteins which cluster in dimers or oligomers and to their DNA sequence and expression vectors or host cells comprising this DNA sequence.

  • Publication number: 20110105742
    Abstract: Object matter of the invention is an optimized DNA sequence encoding the scFv(FRP5) antibody fragment. This novel sequence prevents the generation of the undesired by-product in the context of an scFv(FRP5)-ETA fusion protein, and possibly also other bacterially expressed scFv(FRP5)-containing fusion proteins. The DNA sequence of the scFv(FRP5) domain of scFv(FRP5)-ETA was modified by exchanging a distinct codon, thereby preventing an otherwise possible internal start of protein translation.

  • Patent number: 7892833
    Abstract: Compounds can be used to act as inhibitors of enzymes having histone deacetylase activity for the medical therapy of conditions which predispose a person for the development of a disease, such as but not limited to cancer, inflammatory or metabolic diseases. Such conditions are linked to genetically inherited mutations of crucial genes which predispose a person with this condition to develop the disease phenotype. Thus, such compounds can be used for a suppressive therapeutic approach—the SUPPRESSION THERAPY—in order to inhibit or delay the onset or progression of the genetically predisposed disorder. Furthermore, a clinically used medicament can be manufactured for the SUPPRESSION THERAPY of such inherited predisposing conditions.
