The invention relates to a complex of specifically complex-forming proteins which are not naturally occurring, comprising the following components: a) at least one ligand specific for a target structure, b) at least one protein comprising a mutated dimerization domain, the mutated dimerization domain having been derived by mutation of a naturally occurring dimerization domain, it being possible for this mutated dimerization domain to interact specifically with component c) and the component b) being connected covalently to the component a), c) at least one protein comprising a mutated dimerization domain, the mutated dimerization domain having been derived by mutation of a naturally occurring dimerization domain, it being possible for this mutated dimerization domain to interact specifically with component b) and the component c) is linked covalently to the component d), and d) at least one effector. In addition, the invention relates to the use and preparation of these complexes, and to nucleic acid constructs coding for the proteins mentioned and use thereof.

Complex-forming proteins

A DNA sequence is described for the gene therapy of diseases associated with the immune system. In its essential elements, the DNA sequence is composed of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated in a cell-specific or virus-specific manner and this activation is regulated by the promoter module in a cell cycle-specific manner. The choice of activator sequence and active substance depends on the indication area. The DNA sequence is inserted into a viral or non-viral vector which is supplemented by a ligand having affinity for the target cell. Depending on the choice of activator sequence and active substance, the following can be treated by administering the DNA sequence: defective formation of blood cells; autoimmune diseases and allergies and, in addition, rejection reactions against transplanted organs; chronic arthritis; viral and parasitic infections and, in addition, prophylaxis of viral, bacterial and parasitic infections; and leukemias.

Cell-specific active compounds regulated by the cell cycle

The invention refers to a nucleic acid construct comprising at least one activator sequence, at least one chimeric promoter module comprising a nucleotide sequence which binds a protein of the E2F family and a protein of the CDF-1 family, and at least one gene, wherein said chimeric promoter module promotes expression of the gene in the cell cycle later than the B-myb promoter but earlier than the cdc25C promoter. The invention also concerns the purification and identification of CDF-1 protein, and use of this protein to develop new control systems.

Nucleic acid construct for the cell cycle regulated expression of structural genes

A DNA sequence is disclosed for the genetic therapy of diseases of the central nervous system. The essential components for the DNA sequence are the activator sequence, the promoter module, and the active substance coding gene. The activator sequence is specifically activated in activated endothelial or glial cells. Activation is cell cycle-regulated by the promoter module. The active substance represents an inhibitor of the nerve growth factor, a dopanine metabolism enzyme, and/or a nerve cell protection factor. The disclosed DNA sequence is inserted into a viral or non-viral vector, supplemented with a ligand with affinity for the target cells.
