the ligand-binding subunit of the human 5-hydroxytryptamine1a ( 5-ht1a ) receptor transiently expressed in cos-7 cells and of the native human 5-ht1a receptor derived from hippocampus and frontal cortex were identified by photoaffinity labeling with n- ( p-azido-m- [ 125i ] iodophenethyl ) spiperone [ ( 125i ] n3-naps ) , previously characterized as a high affinity radioiodinated d2-dopamine receptor probe .
