Patent ID: 11384120

Abstract:
The present invention pertains to: a peptide having ATF3-binding ability and represented by any one amino acid sequence selected from the group consisting of SEQ ID NOs: 1 to 4; a fused peptide in which a cell-permeable peptide is bound to the peptide having ATF3-binding ability; and a use of the peptides for the treatment of inflammatory diseases, metabolic diseases, autoimmune diseases and/or fibrotic diseases. According to the present invention, a novel peptide having the ability to bind to ATF3, which is a protein serving as a biomarker and an important factor in the occurrence of various inflammatory diseases, metabolic diseases, autoimmune diseases and/or fibrotic diseases, is provided to thereby regulate the intracellular concentration of ATF3, and can thus be used for the treatment of inflammatory diseases, metabolic diseases, autoimmune diseases and/or fibrotic diseases. Moreover, the disease treatment effect can be enhanced by further fusing a peptide having intracellular permeability and an inflammation inhibitory function to the peptide.
