  • Publication number: 20230287073
    Abstract: A thermally stable polypeptide having FGF7 activity is provided. The polypeptide is a thermally stable polypeptide having FGF7 activity, wherein, in SEQ ID NO: 1, a 120th alanine (A) is substituted with cysteine (C), one including at least one substitution selected from substitution of a 126th lysine (K) with aspartic acid (D) and a 178th lysine (K) with glutamic acid (E) or aspartic acid (D) forms a salt bridge with a 175th arginine (R), and a 133rd cysteine (C) and a 137th cysteine (C) are disulfide bonded.

  • Patent number: 8975369
    Abstract: The present invention relates to a novel protein skeletal module which increases the binding affinity or binding specificity of active polypeptides. More particularly, the present invention relates to a protein skeletal module comprising polypeptides consisting of the 1st to 19th amino acids of the amino acid sequence expressed in sequence number 1; polypeptides comprising active polypeptides; and polypeptides consisting of the 29th to 86th amino acids of the amino acid sequence expressed in sequence number 1. The present invention also relates to a method for preparing the protein skeletal module. The protein skeletal module of the present invention increases the binding affinity or binding specificity of active polypeptides embedded therein, and therefore is effective in diagnosing and treating diseases.
