FUSION PROTEIN COMPRISING THYROTROPIN RECEPTOR VARIANTS AND USE THEREOF

摘要

Disclosed are a fusion protein comprising a thyrotropin receptor (TSHR) fragment and the use thereof. More specifically, disclosed are a fusion protein comprising a TSHR fragment comprising an extracellular domain of a wild-type TSHR and having a substitution of an amino acid at specific position and an immunoglobulin Fc region or a carboxy-terminal cap (C-CAP), and the use thereof. The fusion protein has improved pharmaceutical efficacy, in-vivo persistence and protein stability and a pharmaceutical composition containing the fusion protein as an active ingredient is useful as a therapeutic agent or diagnostic reagent for the alleviation of Graves' disease and Graves' ophthalmopathy.
