Muscarinic Acetylcholine Receptor 1 (CHRM1) and Dopamine Receptors D2 and D3 play significant roles in neurotransmission. CHRM1 also known as M1 receptor is a G protein-coupled receptor with a mass of approximately 51 kDa. It is primarily found in the central nervous system particularly regions like the cerebral cortex and hippocampus. Dopamine Receptors D2 and D3 both belonging to the dopamine receptor family are expressed in brain regions like the striatum and frontal cortex. These receptors modulate neurotransmitter activity by interacting with their ligands acetylcholine and dopamine respectively.

Biological function summary

These receptors are involved in cognitive functions and motor control. CHRM1 participates in mediating cholinergic signals that influence learning and memory. It functions as part of a complex with other muscarinic receptors affecting neuronal excitability and signal transduction. Dopamine Receptors D2 and D3 regulate dopaminergic pathways important for movement and reward processing contributing to controlling behavior through dopaminergic synapses.

Pathways

Muscarinic Acetylcholine Receptor 1 integrates into the cholinergic signaling pathway. This pathway plays a substantial role in modulating neurotransmission and synaptic plasticity. Dopamine Receptors D2 and D3 integrate into dopaminergic signaling pathways important in regulating the release of dopamine impacting mood and emotional response. These receptors share pathways with proteins such as G-proteins which are involved in signal transduction and cellular responses.

These receptors are associated with neurological and psychiatric conditions. CHRM1 is linked to Alzheimer's disease due to its involvement in cognitive function and memory. Changes in muscarinic receptor activity have been observed in patients with this condition affecting signal transmission. Dopamine Receptors D2 and D3 are implicated in diseases like schizophrenia often associated with dopamine dysregulation. Alterations in these receptors' activity influence symptoms and treatment responses. Both are connected to proteins involved in neuropsychiatric disorders such as neurotransmitter transporters and enzymes regulating neurotransmitter synthesis.
