dopamine neurotransmitter receptor activity

Definition

Target type: molecularfunction

Combining with the neurotransmitter dopamine to initiate a change in cell activity. [GOC:PARL, IUPHAR_GPCR:1282, PMID:21711983]

Dopamine neurotransmitter receptor activity involves the recognition and binding of dopamine, a neurotransmitter, to specific receptors on the surface of cells. This interaction triggers a cascade of intracellular signaling events that ultimately modulate neuronal activity. The molecular function can be broken down into the following steps:

1. **Ligand Binding:** Dopamine, acting as a ligand, binds to its specific receptor, which can be either a G protein-coupled receptor (GPCR) or a tyrosine kinase receptor. This binding event initiates a conformational change in the receptor protein.

2. **Signal Transduction:**
- **GPCRs:** The conformational change in the GPCR activates a G protein, which in turn activates effector enzymes such as adenylyl cyclase or phospholipase C. These enzymes produce intracellular second messengers like cAMP or diacylglycerol, respectively.
- **Tyrosine Kinase Receptors:** The conformational change in the tyrosine kinase receptor leads to its autophosphorylation, which activates the receptor's enzymatic activity. This activation initiates downstream signaling pathways involving the phosphorylation of other proteins.

3. **Cellular Response:** The second messengers or phosphorylated proteins generated by the activated signaling pathways ultimately lead to changes in neuronal activity. These changes can include:
- Alteration in ion channel permeability, leading to changes in membrane potential and neuronal excitability.
- Modulation of gene expression, impacting the production of proteins involved in neuronal function.
- Regulation of synaptic plasticity, influencing the strength and efficacy of neuronal connections.

Dopamine receptor activity is crucial for a wide range of physiological processes, including:
- **Movement:** Dopamine signaling in the basal ganglia is essential for controlling voluntary movement and motor coordination.
- **Motivation and Reward:** Dopamine plays a key role in reward-seeking behavior, motivation, and pleasure.
- **Cognition and Attention:** Dopamine is involved in cognitive functions such as attention, working memory, and decision-making.
- **Mood and Emotion:** Dopamine contributes to mood regulation, and imbalances in dopamine signaling are implicated in mood disorders such as depression.

Understanding the molecular function of dopamine neurotransmitter receptor activity is essential for developing therapies for neurodegenerative diseases like Parkinson's disease, addiction, and mental health disorders.'

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
