A fusion protein comprising a target protein, a first recombinant viral coat protein, a second recombinant viral coat protein and a first linkage peptide is provided. The target protein is at N-terminus of the first recombinant viral coat protein. The first recombinant viral coat protein is linked to N-terminus of the first linkage peptide. The second recombinant viral coat protein is linked to C-terminus of the first linkage peptide. The first and second recombinant viral coat proteins are derived from the coat protein (CP) of alfalfa mosaic virus (AIMV). The fusion protein may further comprise a second linkage peptide between the target protein and the first recombinant viral coat protein. The fusion protein may form a virus like particle (VLP). The target protein may be displayed on the surface of the VLP. Also provided are methods for producing the fusion protein and the VLP as well as the uses of the fusion protein and/or the VLP.

Covalently fused viral coat proteins for the display of target molecules

A fusion protein comprising a first recombinant viral coat protein, a second recombinant viral coat protein and a first linkage peptide is provided. The first recombinant viral coat protein is linked to N-terminus of the first linkage peptide. The second recombinant viral coat protein is linked to C-terminus of the first linkage peptide. The first and second recombinant viral coat proteins are derived from the coat protein (CP) of alfalfa mosaic virus (AIMV). The fusion protein may form a virus like particle (VLP). Where the fusion protein further comprises a target protein, the target protein may be displayed on the surface of the VLP. Also provided are methods for producing the fusion protein and the VLP as well as the uses of the fusion protein and/or the VLP.

Recombinant carrier molecules having amino acid sequences from thermostable enzymes and methods of use for expression, recovery and delivery of foreign sequences (peptides and polypeptides) produced in different systems (bacteria, yeast, DNA, cell cultures such as mammalian, plant, insect cell cultures, protoplast and whole plants in vitro or in vivo are provided. The recombinant carrier molecule using sequences from lichenase B (Lic B) were also made and used as part of carrier protein to express, recover and deliver a variety of target polypeptides of interest.
