POLYPEPTIDES WITH PHASE TRANSITION, TRIBLOCK POLYPEPTIDES OF THE POLYPEPTIDE-CALMODULIN-POLYPEPTIDE WITH MULTI-STIMULI RESPONSIVENESS, HYDROGEL OF THE TRIBLOCK POLYPEPTIDES, AND ITS USES

摘要

Disclosed is a polypeptide having a phase transition behavior, wherein the polypeptide consists of a Val-Pro-Gly-Xaa-Gly pentapeptide repeat or a Val-Pro-Ala-Xaa-Gly) pentapeptide repeat, and the polypeptide includes a [Val-Pro-Gly-Xaa-Gly]n or a [Val-Pro-Ala-Xaa-Gly]n (SEQ ID NO:2) pentapeptide repeat. In addition, the present invention provides a multi-stimuli polypeptide composed of polypeptide-calmodulin-polypeptide having a phase transition behavior and a hydrogel prepared using the same. A dynamic protein hydrogel according to the present invention may be used as a drug carrier, as a scaffold for tissue engineering or as a kit for tissue or organ regeneration.
