D 5 receptor is a subtype of the dopamine receptor that has a 10-fold higher affinity for dopamine than the D 1 subtype. [6] The D 5 subtype is a G-protein coupled receptor, which promotes synthesis of cAMP by adenylyl cyclase via activation of Gα s/olf family of G proteins. [7] [8] Both D 5 and D 1 subtypes activate adenylyl cyclase.
Interactions between catechol-based agonists and three trans-membrane serine residues including S1985.42, S1995.43, and S2025.46 function as microswitches that are essential for receptor activation. [43] Dopamine D1 CryoEM structure in complex with dopamine (PDB code: 7LJD), Dopamine D1 receptor in orange, dopamine in cyan, interactions are in ...
The D 1-like receptors are a subfamily of dopamine receptors that bind the endogenous neurotransmitter dopamine. [1] The D 1-like subfamily consists of two G protein–coupled receptors that are coupled to G s and mediate excitatory neurotransmission, of which include D 1 and D 5. [2]
Dopamine receptors are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling. Abnormal dopamine receptor signaling and dopaminergic nerve function is implicated in several neuropsychiatric disorders. [2]

It is one of the four major dopamine pathways in the brain. It is essential to the normal cognitive function of the dorsolateral prefrontal cortex (part of the frontal lobe), and is thought to be involved in cognitive control , motivation , and emotional response.
The dopamine receptors are members of the G protein-coupled receptors superfamily with seven transmembrane domains. Dopamine receptors have five subtypes, D 1 through D 5, the subtypes can be divided into two subclasses due to their mechanism of action on adenylate cyclase enzyme, D 1-like receptors (D 1 and D 5) and D 2-like receptors (D 2, D ...
Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
