FIELD: medicine.
SUBSTANCE: invention refers to immunology. Presented are anti-Dickkopf 1 (anti-Dkk-1) antibodies and their functional fragments specified among the antibodies: 1) containing CDR1 VH containing the amino acid sequence SSYAIS, SYAIS or GFTFSSY; CDR2 VH containing the amino acid sequence SVSGTGLGFGTYYPDSVKG or SVSGTGLGFGTY; and CDR3 VH, containing the amino acid sequence TSLENYAFDY or SLENYAFDY; and CDR1 VL containing the amino acid sequence RASESVDDFGISFIN; CDR2 VL containing the amino acid sequence AGSKQGS; and CDR3 VL containing the amino acid sequence QQLKEVPPT; and 2) the antibodies disclosed in Table 4 presented in the application materials. Described are: nucleic acids coding the above antibodies or their functional fragments; expression vectors containing the above nucleic acids; and cells used for expression of the above antibodies or their functional fragments and containing the above expression vectors. Presented is a method for producing the antibody or its functional fragment involving the stage of culturing the above expression cell. Disclosed is a composition possessing Dkk-1 binding activity, containing the antibody or its functional fragment in a therapeutically effective amount and a pharmaceutically acceptable excipient, thinner or carrier.
EFFECT: invention enables extending the range of products for treating the diseases associated with Dkk-1 and LRP5/6 excessive reaction, which cause Wnt activation.
