Ver/Editar Humano

O receptor D₄ de dopamina é um receptor acoplado à proteína G, codificado pelo gene DRD4.^[3] Tal como outros tipos de receptores de dopamina, o receptor D₄ é activado pelo neurotransmissor dopamina. É também um alvo para drogas que tratam a esquizofrenia e a doença de Parkinson.

Factos rápidos DRD4, Identificadores ...

O receptor D₄ é considerado um Receptor D2 de dopamina, no qual o receptor activado inibe a enzima adenilato ciclase, reduzindo assim a concentração intracelular do mensageiro secundário AMP cíclico.^[4]
