    摘要: Compositions and methods for the inducible expression of genes in eukaryotic cells are provided. Expression of a nucleotide sequence of interest encoding a protein of interest is controlled by a regulatory fusion protein that consists of a transcription blocking domain and a ligand-binding domain. When a cognate ligand for the ligand-binding domain is present, transcription of the nucleotide sequence of interest is blocked. Upon removal of the cognate ligand, the nucleotide sequence of interest is transcribed. The method is useful for large scale bioreactor production of a desired protein of interest in eukaryotic cells.

    摘要: A fusion polypeptide comprising (A)x-M-(A′)y, wherein A and A′ are each polypeptides capable of binding a target receptor. The fusion polypeptides of the invention form multimeric proteins which activate the target receptor. A and A′ may be each be an antibody or fragment derived from an antibody specific for a target receptor, such as the same or different ScFv fragments, and/or a ligand or ligand fragment or derivative capable of binding the target protein, M is a multimerizing component, and X and Y are independently a number between 1-10.
