Estimating the term…
The present invention relates to the generation of specific binding partners binding to (poly)peptides encoded by genomic DNA fragments or ESTs. The (poly)peptides are expressed as part of fusion proteins which are forming inclusion bodies on expression in host cells. The inclusion bodies are used to generate binding partners which bind specifically to said (poly)peptides. The specific binding partners, in particular immunoglobulins or fragments thereof, are useful for analysis and functional characterisation of proteins encoded by nucleic acid sequences comprising the corresponding genomic DNA fragments or ESTs. The invention further relates to nucleic acid molecules, vectors and host cells to be used in the methods of the present invention. The invention further relates to the use of fusion proteins comprising the first N-terminal domain of the geneIII protein of filamentous phage as fusion partner for the expression of a (poly)peptide/protein fused to said fusion partner, and to methods for the expression of (poly)peptide/proteins.
A method for generating a specific binding partner to a (poly)peptide which is encoded by a nucleic acid sequence comprised in a genomic DNA fragment or an expressed sequence tag (EST) comprising:
A nucleic acid molecule encoding a fusion protein comprising aa) the first N-terminal domain of the geneIII protein of filamentous phage and ab) a (poly)peptide which is encoded by a nucleic acid sequence comprised in a genomic DNA fragment or an expressed sequence tag (EST), wherein said nucleic acid molecule does not comprise a nucleic acid sequence encoding a signal sequence for the transport of the fusion protein to the periplasm of a bacterial host cell.
The use of a fusion protein comprising the first N-terminal domain of the geneIII protein of filamentous phage as fusion partner for the expression of a (poly)peptide/protein fused to said fusion partner, wherein said fusion protein is obtained in the form of inclusion bodies.
A method for the expression of a (poly)peptide/protein comprising:
