1 Alanine-substituted mutants of TM7 of the beta(2)AR showed that Tyr(308,) located at the top of TM7, mainly contributed to beta(2) selectivity. Tyrosine adrenoceptor beta 2 Homo sapiens
2 Three-dimensional models built on the basis of the predicted structure of rhodopsin showed that Tyr(308) of the beta(2)AR covered the binding pocket formed by TM2 and TM7 from the upper side, and Thr(117) of the beta(1)AR located in the middle of the binding pocket to provide a hydrogen bonding for the beta(1)-selective agonists. Tyrosine adrenoceptor beta 2 Homo sapiens
