Abstract: The present invention is directed to proteins of natural origin and materials made therefrom, in particular to threads, fibers, foams and gels derived therefrom. The invention further provides the use of these proteins/threads and materials in the field of technology, biotechnology and/or medicine, in particular in the manufacture of wound closure or coverage systems, suture materials and in the manufacture of replacement materials, preferably artificial cartilage or tendon materials, as well as in other commercial applications.

Abstract: The present invention provides novel polypeptides comprising a prion-aggregation domain and a second domain; novel polynucleotides encoding such polypeptides; host cells transformed or transfected with such polynucleotides; novel fibrils with specific functionalities and unusually high chemical and thermal stability; and methods of making and using the foregoing.
