SELF-ASSEMBLING SYNTHETIC PROTEINS Russian patent published in 2021 - IPC C07K14/28 C07K14/435 C07K14/475 C07K14/485 C07K19/00 A61K39/00 A61P37/00 A61P35/00 

FIELD: biotechnolgy.

SUBSTANCE: invention relates to the field of biotechnology, specifically to recombinant therapeutic proteins, and can be used in medicine for treatment of cancers of the breast, lungs, bladder, ovaries, external female genital organs, colon, pulmonary artery, brain, rectum, intestines, head , neck and esophagus. A synthetic protein based on the mutant B-subunit of the A1B5 group of bacterial holotoxins derived from the B-subunit of cholera toxin (SСT) and connected via a peptide spacer to a polypeptide including the neutralizing domain of human transforming growth factor (TGF) is proposed.

EFFECT: invention provides for production of stable homopentameric structures without loss of the function of TGF-induction of the immune response in mammalian host organisms with the formation of neutralizing antibodies against TGF.
