What are Peptide Fusion Proteins?

At its core, a peptide fusion protein is a protein resulting from the genetic or chemical combination of at least two different peptide or protein sequences作者：B Wu·2014·被引用次数：134—Peptide-Fcfusion proteins(or peptibodies) are chimeric proteins generated by fusing a biologically activepeptidewith the Fc-domain of immunoglobulin G.. This fusion can involve linking a biologically active peptide with a larger protein domain, such as the Fc region of immunoglobulin G (IgG). This strategy, often referred to as creating peptibodies, aims to leverage the specific biological activity of a peptide while enhancing its stability, pharmacokinetic properties, or targeting capabilities by fusing it to a more robust protein scaffold作者：M Sioud·2015·被引用次数：30—Expression and purification ofpeptide-Fcfusion proteins. Thepeptide-Fc fusions were produced by transient transfection of the plasmids into HEK293T cells.. For instance, peptide-Fc fusion proteins have been developed to improve the half-life of therapeutic peptides, making them more effective in vivo.

The concept extends beyond peptide-Fc fusion proteins. Researchers are exploring various combinations, including antibody-peptide fusion proteins, where an antibody fragment is fused with a peptide to create bispecific agents capable of targeting multiple entities simultaneously. Examples include constructs designed to target viral components, such as the MERS-CoV. Another area of interest is the development of cell-penetrating peptide fusion proteins, which utilize the inherent ability of certain peptides to facilitate the entry of larger molecules into cells, thereby enhancing the delivery of therapeutic agents.

Construction and Engineering of Peptide Fusion Proteins

The generation of peptide fusion proteins typically involves recombinant DNA technology. Genes encoding the desired peptide and protein or domain are engineered and ligated together, often with the inclusion of a linker peptide. These linker peptides, such as glycine-serine sequences, are crucial for maintaining the structural integrity and functional activity of the fused components by preventing steric hindrance. The resulting recombinant DNA construct is then expressed in a suitable host system, such as E.2021年3月12日—UsingpeptidePd4 and other alanine substitution combinations of Pd4 attached to a green fluorescentprotein(GFPuv), nanoparticles with well- ... coli or mammalian cells like HEK293T cells, followed by purification of the fusion protein.The antibody-peptide fusion protein, AT-02, is an effective ...
