FUSED PROTEIN ELICITING BIOLOGICAL ACTIVITY OF INTERFERON-ALPHA, DIMERIC FUSED PROTEIN, PHARMACEUTICAL COMPOSITION COMPRISING THEREOF, DNA MOLECULE (VARIANTS) AND METHOD FOR TARGETING INTERFERON-ALPHA INTO LIVER TISSUE
FIELD: genetic engineering, proteins, medicine, pharmacy.;SUBSTANCE: invention relates to a method for preparing a fused protein representing immunoglobulin Fc-fragment and interferon-alpha and can be used in treatment of hepatitis. Method involves construction of a fused protein comprising immunoglobulin Fc-fragment prepared from Ig G1 or Ig G3 in direction from N-end to C-end and the end protein comprising at least one interferon-alpha. Fc-fragment and the end protein are joined directly or by a polypeptide bridge. The fused protein is used for preparing a pharmaceutical composition used in treatment of liver diseases and in a method for targeting interferon-alpha into liver tissues. Invention provides preparing the fused protein eliciting with biological activity of interferon-alpha providing its concentrating in liver and showing enhanced solubility, prolonged half-time life in serum blood and enhanced binding with specific receptors.;EFFECT: improved targeting method, valuable biological properties of fused protein.;10 cl, 5 dwg, 9 ex
