Drd5 — Dopamine Receptor D5 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Dopamine Receptor D5 is a The D5 dopamine receptor is a D1-like receptor with the highest dopamine affinity among D1-family receptors. It is involved in cognitive functions, circadian rhythm regulation, and reward-motivated behavior.

The DR5 gene encodes a G protein-coupled receptor that The D5 dopamine receptor is a D1-like receptor with the highest dopamine affinity among D1-family receptors. It is involved in cognitive functions, circadian rhythm regulation, and reward-motivated behavior.
This receptor couples to G proteins to activate downstream signaling cascades:
| Disease | Role | Evidence |
|---|---|---|
| Parkinson's disease | Receptor alterations affect dopaminergic signaling | GWAS, postmortem studies |
| Schizophrenia | Altered receptor expression and signaling | Genetic association, PET studies |
| Movement disorders | Receptor polymorphisms affect motor control | Clinical studies |
This receptor is expressed in various brain regions:
Expression data available from Allen Brain Atlas.
The study of Drd5 — Dopamine Receptor D5 has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
