Dopamine receptor D 1, also known as DRD1. It is one of the two types of D 1 -like receptor family — receptors D 1 and D 5 . It is a protein that in humans is encoded by the DRD1 gene.
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]
The signalling of the D 1 –D 2 receptor heteromer is distinct from that of the parent receptor monomers. It comprises G q/11 coupling, phospholipase C activation, intracellular calcium release from inositol trisphosphate receptor-sensitive stores, CaMKII activation [2] and BDNF production. [3]
Cell types: Neurons in the nucleus accumbens are mostly medium spiny neurons (MSNs) containing mainly D1-type (i.e., DRD1 and DRD5) or D2-type (i.e., DRD2, DRD3, and DRD4) dopamine receptors. A subpopulation of MSNs contain both D1-type and D2-type receptors, with approximately 40% of striatal MSNs expressing both DRD1 and DRD2 mRNA.
The substantia nigra is located in the ventral midbrain of each hemisphere. It has two distinct parts, the pars compacta (SNc) and the pars reticulata (SNr). The pars compacta contains dopaminergic neurons from the A9 cell group that forms the nigrostriatal pathway that, by supplying dopamine to the striatum, relays information to the basal ganglia.
Dopaminergic cell groups, DA cell groups, or dopaminergic nuclei are collections of neurons in the central nervous system that synthesize the neurotransmitter dopamine. [1] In the 1960s, dopaminergic neurons or dopamine neurons were first identified and named by Annica Dahlström and Kjell Fuxe, who used histochemical fluorescence. [2]
These structures play a role in various memory systems. Furthermore, the drug cocaine elicits its desirable effects by blocking the DRD1 dopamine receptors in the striatum, resulting in increased dopamine levels in the brain. [77] These receptors are important for the consolidation of procedural memory.
