The aim of our study is to identify signalling sensitive residue positions of the glycoprotein hormone receptors (GPHR), especially the thyrotropin receptor (TSHR) on the transmembrane helices (TMH) 5 and 6, knowing to be involved in GPCR activation. We performed modelling driven site-directed mutagenesis to pinpoint residues that are responsible for stabilization of active and inactive conformations of the TSHR.We highlight two amino acids that are high...
