FIELD: genetic engineering, medicine.
SUBSTANCE: invention proposes chimeric protein (ANTH1) consisting of a sequence corresponding to 60 amino acids of N-terminal region of interleukin-2 and extracellular moiety of N-terminal moiety of human gamma-interferon alpha-chain that are bound each with other by peptide Ala-His-Met-Met. Protein ANTH1 possesses capacity to inhibit biological activity of gamma-interferon and/or interleukin-2 and therefore it can be used in preparing drugs designated for treatment of diseases mediated by activity of interleukin-2, gamma-interferon or both these cytokines, in particular, in treatment of cerebrospinal sclerosis, erythematosus lupus, proliferative arthritis, diabetes mellitus and others. Invention can be used in medical-biological industry.
EFFECT: valuable medicinal and biological properties of protein.
