Trimeric chimera protein and collagen matrix containing chimera protein

摘要

Provision of a trimeric chimera protein which has sufficiently retained physiological activity of a physiologically active peptide simultaneously with fibril-forming ability of a collagen. A trimeric chimera protein comprising a collagen and a biologically active peptide fused to the collagen, wherein the biologically active peptide is fused on the side of the amino terminal of the collagen, and the collagen is a fibril-forming collagen having a triple helical structure in its triple helix region. <IMAGE>
