    Abstract: A DDR2(discoidin domain receptor 2) protein having increased kinase activity and a preparation method thereof are provided to offer a target protein so as to develop medicines for treating diseases caused by excessive activation of DDR2 autophosphorylation and kinase activity such as liver cirrhosis, arteriosclerosis, arthritis and cancer. A protein containing a modified human DDR2 cytosolic tyrosine kinase domain having increased autophosphorylation and tyrosine kinase activity is provided, wherein the modified human DDR2 cytosolic tyrosine kinase domain is prepared by modifying at least one of tyrosines 736, 740 and 741 in the activation loop of human DDR2 cytosolic tyrosine kinase domain through induction of tyrosine phosphorylations, or through independent mutation to phenylalanine, alanine or glycine by site-directed mutation. The method for preparing the protein containing modified human DDR2 cytosolic tyrosine kinase domain having increased autophosphorylation and tyrosine kinase activity comprises the steps of: amplifying a DNA fragment encoding the DDR2 cytosolic tyrosine kinase domain protein, and introducing the amplified DNA fragment into a viral expression vector to construct a recombinant viral expression vector for DDR2 cytosolic tyrosine kinase domain protein and to generate a recombinant virus containing the DDR2 cytosolic tyrosine kinase domain protein; amplifying a DNA fragment encoding a full-length c-Src or c-Src related protein, and introducing the amplified DNA fragment into another separate virus expression vector genome to construct a recombinant virus expression vector for the c-Src or c-Src related protein and to generate a recombinant virus containing the c-Src or c-Src related protein; infecting the DDR2 cytosolic tyrosine kinase domain-containing virus and the c-Src or c-Src related protein-containing virus into a host cell, expressing both proteins simultaneously, and inducing the tyrosine phosphorylation at the DDR2 cytosolic tyrosine kinase domain by the tyrosine kinase activity of c-Src or c-Src related protein to produce a large quantity of the protein containing the DDR2 cytosolic tyrosine kinase domain with increased tyrosine phosphorylation; and isolating and purifying the obtained protein containing the DDR2 cytosolic tyrosine kinase domain with increased tyrosine phosphorylation.
