Abstract
Peptides that form lightly associated homodimers can be used to form dimers and multimers of other molecules and molecular motifs of interest. These association peptides can dimerize regardless of whether motifs are added to the amino-terminus of the peptide, or the carboxy terminus of the peptide, although additions to the carboxy-terminus of the association peptides require the presence of certain acidic residues.
Claims10
A method for joining two or more peptides or proteins, said method comprising the steps of:
- (a) attaching an association peptide to either the N- or C-terminus of each of said peptides or proteins to be joined, to form a fusion complex for each of said peptides or proteins to be joined wherein said association peptide comprises the amino acid residue sequence SKVILF (SEQ ID NO:1 ) and wherein the peptides or proteins to be joined together are attached to said association peptide's amino-terminus or to said association peptide's carboxy terminus, provided that if the peptides or proteins are attached to said carboxy terminus, then a free carboxyl group is positioned adjacent to the F residue of said association peptide;
- and
- (b) mixing the fusion complexes resulting from step (a) under conditions that allow said association peptide to dimerize.
