  • One receptor, now termed BXR for benzoate X receptor, was activated by embryonic extracts. (uci.edu)
  • The G protein-coupled and seven-transmembrane receptor, GPR30, is now widely recognized as an estrogen receptor (ER), hence its official new acronym GPER. (nih.gov)
  • Cooperative activity of GR with other transcription factors and a plethora of coregulators contribute to the tissue- and context-specific response toward the endogenous and pharmacological glucocorticoids (GCs). (uni-ulm.de)
