5-HT1A Receptors

The serotonin 5-HT1A receptor was the first 5-HT receptor to be fully sequenced. 5-HT1A receptor binding sites are located primarily in limbic brain areas, notably the hypothalamus and cortical areas. The human gene encoding this receptor has been localized to chromosome 5.

The serotonin 5-HT1A receptor was the first 5-HT receptor to be fully sequenced and the human gene encoding this receptor has been localized to chromosome 5 (5q11.2-q13).

5-HT1A receptor binding sites are located primarily in limbic brain areas, notably the hypothalamus, lateral septum, cortical areas and the mesencephalic raphe nuclei. 5-HT1A receptor ligands with agonist activity possess antianxiety, antidepressant, antiaggressive, and perhaps anticraving, anticataleptic, antiemetic, and neuroprotective properties.
