摘要：
A mutant thyroid stimulating hormone receptor (TSHR) or fragment thereof comprises one or more mutations, wherein the mutant TSHR has increased thermostability with respect to the equivalent wild type TSHR or fragment. The one or more mutation is preferably within the extracellular leucine-rich repeat domain (LRD) of the TSHR, or within residues 22 to 260 (TSHR260) of the TSHR. A mutant TSHR or fragment thereof of the invention preferably consists of, or consists essentially of, the subdomain TSHR260 of the TSHR receptor. The mutants may be P28E, L59F, T62V, H63C, L64Y, R112P, P142I, D143P, D151E, S166T, I167F, P168Y, V169R, N170W, T179C, I253R OR R255Y. A mutant TSHR or fragment thereof according to the invention has a greater thermostability than the equivalent wild type TSHR or fragment as determined by its half-life at a given temperature.
