« Hide More detailed introduction

Thyrotropin-releasing hormone (TRH) receptors (provisional nomenclature as recommended by NC-IUPHAR [2]) are activated by the endogenous tripeptide TRH (TRH, P20396) (pGlu-His-ProNH2). TRH (TRH, P20396) and TRH analogues fail to distinguish TRH1 and TRH2 receptors [5]. [3H]TRH (human, mouse, rat) is able to label both TRH1 and TRH2 receptors with Kd values of 13 and 9 nM respectively. Synthesis and biology of ring-modified L-Histidine containing TRH analogues has been reported [3].
