제목 Elastin Fusion Proteins with Coiled-coil Domains for Stimuli-triggered Self-assembly
초록 Stimuli-responsive self-assembly of protein-based biomaterials have been studied for various biomedical applications such as drug delivery, tissue engineering and regenerative medicine. In this study, we report molecular design, biosynthesis, purification and characterization of elastin fusion proteins with coiled-coil domains for stimuli-triggered self-assembly. We showed that the elastin-based polypeptide (EBP) middle block provided thermally-triggered aggregated domains above its lower critical solution temperature (LCST) while coiled-coil domains at both ends forming intra- or intermolecular physical cross-linking due to their amphipathic characteristics. The stimuli-triggered self-assembly of the elastin fusion proteins with coiled-coil domains would open a new avenue for physically cross-linked protein-based micelles and hydrogels.
