A NOVEL PROTEIN AND PROCESS FOR PREPARING THE SAME
摘要
A protein comprising an amino acid sequence represented by SEQ ID NO: 1 in t he Sequence Listing and originating in human MP52 and the dimer of this protein. This dimer protein can be obtained by constructing a plasmid containing a DNA wherein a codon encoding methionine is added to the 5' end of a DNA sequence encoding the above- mentioned aminoacid sequence, transforming Escherichia coli by this plasmid, incubating the E. coli transformant, solubilizing and purifying the obtained inclusion body to thereby give a monomer protein, and then renaturing the obtained monomer protein into the dimer followed by purification. This dimer protein is useful in the treatment of cartilage and bone diseases.
